EA Files Patent For Online Matchmaking Algorithm To Boost ‘Player Engagement’

Matchmaking is the existing automated process in League of Legends that matches a player to and against other players in games. Contents [ show ] Details The system estimates how good a player is based on whom the player beats and to whom the player loses. It knows pre-made teams are an advantage, so it gives pre-made teams tougher opponents than if each player had queued alone or other premades of a similar total skill level Riot Games Inc. The basic concept is that the system over time understands how strong of a player you are, and attempts to place you in games with people of the same strength. As much as possible, the game tries to create matches that are a coin flip between players who are about the same skill. The basic priorities of the system are, in order of importance: Protecting new players from experienced ones.

Connectivity A Dating Site for Algorithms A startup called Algorithmia wants to connect underused algorithms with those who want to make sense of data. A startup called Algorithmia has a new twist on online matchmaking. Its website is a place for businesses with piles of data to find researchers with a dreamboat algorithm that could extract insights—and profits—from it all.

One of the biggest complaints about any competitive multiplayer game is the matchmaking. Developers pore over all sorts of details in order to make matchmaking algorithms beneficial for players.

Clearly for a good result one wishes to have: For some types of games it is possible to enhance the scheduling even more by having a mild victory-point scale rather than pure win-loss for each match. The mechanics of matching entrants at each round involve first sorting by win-loss record or VP’s if applicable , and then working from both ends to the middle. In case of a severe conflict near the end of the event ie teams having to replay each other , Bridge tournaments have a policy of forcing this replay as far down the standings as possible, without creating another such conflict.

Also, to maintain interest at the low end, it is common in larger Bridge tournaments to take the bottom half of the entrants at the half-way point and start a second new event. Better players have been know to term this The Swamp. In world-championship Bridge tournaments, a complex combination of qualifying Swiss, followed by double-elimination knock-out with repechage is used. I admit to never having explored the intricacies of this, but a search of relevant regulations for Bridge Olympiads in particular should provide details for this mechanism.

Activision’s patented method to drive microtransactions with matchmaking

Matchmaking Improvements First off is an overhaul to matchmaking in PvP. Make sure to check it out for all the details. Rosters are a thing of the past; now you can simply join with your party. Players now have to confirm before entering a match, so 4v5 situations can no longer occur from people going AFK. For players who do drop out, the Dishonor system has also been improved to better handle bad behavior. PvP is now grouped into three areas:

Using an existing scheme e. ELO or the Microsoft research developed formulas http: Once you have your magic number, a lot of considerations come in, as to your and your players preferences. My design goals were: Make it run fast no long iterations for improvements of the team balance , given that there might be players, of which a few hundred in the queue, to be assigned to maybe games to be started, getting too scientific is maybe not a good idea.

Make no attempt to optimize across multiple new games to be started at a given time. Try to give players a gaming experience at their own skill level, by not staffing teams with absolute newbies and pro-gamers alike. The pool is sorted descending by player rating. Doing this, results in Team A being always better or equally strong as Team B.

Call ImproveTeams with the information of team a, team b and the remainder of the pool. ImproveTeams iterates both teams, computes the skill delta, and then depending on whether it is a positive or negative number shuffles the players on the same position in the arrays of both teams. The same could be applied to the players remaining in the pool, after the first match is paired, until the server capacity free game-slots is exhausted or the player pool is empty. Bad players have longer waiting times as they are always handled last.

Last March, EA also filed two different patents for the same purposes. The concept is not a new one and has been toyed with for years, although EA is attempting to patent a specific version of this system with their own innovations. The second patent is much more complex but potentially problematic. Accompanying the patent is a technical document detailing the arguments as to why EOMM is a worthwhile endeavor for online games, including theoretical findings and use of EOMM as a metric against standard online matchmaking.

The short version of the patent is this:

Second, we need to add latency to our matchmaking algorithm so that you are all grouped on an instance of the district that is closest to most of the players. Lastly, in an ideal scenario, we would collapse down to a single World with multiple servers in North America, Europe and Asia.

References Alternating and Augmenting Paths Graph matching algorithms often use specific properties in order to identify sub-optimal areas in a matching, where improvements can be made to reach a desired goal. Two famous properties are called augmenting paths and alternating paths, which are used to quickly determine whether a graph contains a maximum, or minimum, matching , or the matching can be further improved.

The goal of a matching algorithm, in this and all bipartite graph cases, is to maximize the number of connections between vertices in subset , above, to the vertices in subset , below. Unmatched bipartite graph Most algorithms begin by randomly creating a matching within a graph, and further refining the matching in order to attain the desired objective.

Random initial matching , , of Graph 1 represented by the red edges , with the matching, , is said to have an alternating path if there is a path whose edges are in the matching , , and not in the matching, in an alternating fashion. An alternating path usually starts with an unmatched vertex and terminates once it cannot append another edge to the tail of the path while maintaining the alternating sequence.

An alternating path in Graph 1 is represented by red edges, in , joined with green edges, not in.

Share Copy Just a few months ago we learned that Activision has patented a matchmaking algorithm to encourage microtransaction and now EA has also filed a patent for a matchmaking algorithm although theirs is to boost player engagement in online games, however, this algorithm can potentially be tuned to drive microtransactions. EA has filed patents for two different matchmaking algorithms and both of them focus on driving players engagement in games. The first patent is an algorithm that dynamically changes the difficulty for players based on their performance in the game.

Which might not sit well with players who purposefully play at a higher difficulty to challenge themselves. According to the patent, this matchmaking algorithm takes a lot of things into account like player skill level, play style, and more and will matchmake players according to that.

Random Article Blend One of the biggest complaints about any competitive multiplayer game is the matchmaking. Developers pore over all sorts of details in order to make matchmaking algorithms beneficial for players. Well, Valve is stepping outside the box and making matchmaking variables based on your behavior in other games. Over on the official Counter-Strike website , there’s an update for the game called “The Trust Factor”. This is a replacement system for the previous model known as the “Prime Matchmaking” system.

In the “Prime Matchmaking” players would have to attach a unique phone number to their account, and they would be paired up based on their in-game experience. This created fractures for some players because it meant that if you enjoyed being matched up with or against certain groups of players, those who ranked up or didn’t rank up fast enough would eventually be moved out of the matchmaking pool.

According to Valve, this created what the team referred to as a “hard boundary” for the Counter-Strike: Instead of relying on the strict boundaries of the previous system, Valve decided to re-imagine a new system based on observable player behavior. Instead of matchmaking based on strict, arbitrary variables, the developers decided to experiment with creating an algorithm based on the conditional variables of a player’s account behavior and attributes from their Steam profile.

For instance, the algorithm takes into account how often an account was reported for cheating; how often the account spent playing certain games; and whether or not the account was VAC banned at any point. According to the post, the experimental results have been positive so far, and Valve will be ditching the parts of the old system that didn’t work in favor of the new “Trust Factor Matchmaking“. The post explains that players can’t know exactly what factors and variables will account for the totality of how an account is gauged for the Counter-Strike:

Activision Patents Algorithm To Make Gamers Spend

Share on Reddit The practice of incorporating micro transactions and loot boxes into video games has grown from sporadic to omnipresent in recent years. But in-game items like loot boxes—which commonly appear in multiplayer games—are worthless to publishers if players don’t engage with them. Game publisher Activision has already patented a way to drive in-game purchases by manipulating “matchmaking,” or how players are paired up with strangers in online multiplayer games. This week, eagle-eyed YouTuber YongYea deserves credit for discovering a similar, though not identical, matchmaking-manipulation scheme being researched and promoted by researchers at game publisher EA.

Jul 31,  · Matchmaking two random users is effective, but most modern games have skill based matchmaking systems that incorporate past experience, meaning that users are matched by their skill. Every user should have a rank or level that represents their r: Stephen Blum, Todd Greene.

Casual Play[ edit edit source ] Casual Play mode matchmaking includes a new player pool. Players are initially placed in a separate pool, allowing them to play exclusively against other new players. After a certain period, players are introduced into the main matchmaking pool. Pairings are therefore affected not only by each player’s rating or rank, but by which other players are currently awaiting matchmaking. For example, different times of day often attract different types of players, with certain times typically featuring a slightly more competitive pool of players.

Because of this, each type of ranking is entirely accurate only for that same quality of population. Such variations are not fixed, and may vary by day, time of day, or in relation to calendar or game-related trends. Because wins and losses will ultimately result in an adjusted rating or rank, such variance can also lead to a yo-yo effect with pairings.

For example, a player who normally plays Casual Play mode in the mornings may try playing at another time of day, only to find the competition more fierce. This discrepancy in the player’s matchmaking will likely lead to the player losing several games in a row, resulting in the player’s MMR dropping rapidly in order to select opponents of equal ability. However, should that player then return to playing in the mornings, they may find the opponents selected for them to be extremely easy to defeat, due to the adjustment of their MMR.

Bias[ edit edit source ] A common complaint from players is that the matchmaking system is intentionally matching them against opponents using decks designed to beat them.

The trick is to use the hypothetical chance of drawing with someone else: If you are likely to draw with another player then that player is a good match for you! Players may wish to evaluate their skills relative to people they know or relative to potential opponents they have never played, so they can arrange interesting matches.

Talk about a kick in the face I can’t unbuild my accounts all six of them and I’m not going to build new ones I hate engineering. It is my belief that they’re really not out to make adjustments at all. Been playing for over 4 years it’s the same old thing over and over again hey chief we’re working on it be patient blah blah blah Sounds like they gave you actual advice.

Only in the forums is the view prevalent that maxing a base defenses yields an advantage in war matching. But read the thread titles on the first page. Open any thread and read the posts. Page after page of complaints about matching against engineers. For every one of those posts complaining about being matched against an engineer there is another side, a clan for whom engineering worked. There has never been a plan to punish engineers.

Or force engineers to play differently.
