美国大学生数学建模竞赛（MCM/ICM）由美国数学及其应用联合会主办，是唯一的国际性数学建模竞赛，也是世界范围内最具影响力的数学建模竞赛。 本文档为作者参加2020美赛时总结，并且获得了F奖的佳绩，希望对大家有帮助！

里面有数学建模大多数的算法，包括对应的代码，都是我自己整理的

详细整理了2010-2020年美赛的各个问题，所有数据文件也已经打包；包括2010年开始直到2020年的每一个赛题的题面，题目附件，其余注释和参考文献链接。主要文件在pdf中，一部分已经是pdf格式的直接在目录中

文档是小组参与2020美赛建模F题的提交论文，最后获得Meritorious Winner（一等奖）

文件里保存了2020年的美赛题目，我是三月份参加的比赛，把题目保存下来供自己和各位要参加比赛的同学练习

summary: In this paper, we establish a regression model based on the passing network to evaluate the influence of team structure strategy and opponents’ counter-strategy on the match results. Fortask1,wefirstlistsomeHuskiesmatchstatisticsforthisseasonandanalyzetheteamin brief. Secondly, we construct a passingnetwork based on the number of passes and visualizes the passing network diagram of three games under three different coaches. We use these three diagrams to describe and compare the changes in Huskies’ strategies. After that, we identify network patterns of dyadic and triadic configurations and count 15 kinds of these two configurations in the above three matches, reflecting the structural indicators of the passing network. We also explore time scale and micro scale by giving the change of the team’s centroid over time in the first match and the Huskies’ 4 positions heat map over the season. For task 2, we construct the regression model not only introducing the basic data representing Huskies’ and opponents’ ability, but also extracting six independent variables from the indicators of the passing network into the model. Considering opponents’ counter-strategies, we also introduce the product interaction term between opponents’ data and network structure indicators. Through the training of regression model, we can judge whether the independent variables introduced have influence, what kind of influence and how much influence the independent variables introduced have on the result of the match. For task 3, by bringing in data for training, the model leaves 10 variables including interactionterms. Inordertoverifytheaccuracyofthemodel,weuseLeaveOneOutcrossvalidation, andthepredictedaccuracyoftheraceresultreached71.05%. Then,basedonthetrainedmodel, we point out the effective structural strategies Huskies currently have, such as the strong connection between the core players. Meanwhile, we also give specific advice for Huskies team to improve team success, such as the emphasis on triadic configurations among players. Fortask4,weextendthemodelappliedtohuskiestoallteamworkscenariosandintroduce the IPOI model. The IPOI model conducts multi-level induction of influencing factors and selection of assessment indicators from the four aspects of team input, process, output and reinput, taking into account team construction, operation, management, feedback and other aspects.
