Matchmaking is a core task in e-sports and online games, as it contributes to player engagement further influences the game's lifecycle. Previous methods focus on creating fair games at all times. They divide players into different tiers based skill levels only select from same tier for each game. Though this strategy can ensure matchmaking, not always good engagement. In paper, we propose novel Engagement-oriented (EnMatch) framework simultaneously enhance Two main issues need be addressed....
