您好!演化博弈是一个研究博弈策略演变的领域。如果您需要MATLAB代码来模拟演化博弈,可以参考以下代码:
```
function [strategy, scores] = evol_game(n, T, S, P)
% n: number of players
% T: number of rounds
% S: score matrix (n x n)
% P: initial probability distribution over strategies (n x 1)
% Initialize the strategy and scores
strategy = zeros(n, T);
scores = zeros(n, T);
% Play the game
for t = 1:T
% Calculate the payoffs for each player
for i = 1:n
for j = 1:n
scores(i, t) = scores(i, t) + P(j) * S(i, j);
end
end
% Update the strategy probability distribution
P = P .* exp(scores(:, t) / (n * T));
P = P / sum(P);
% Record the strategy for each player
[~, strategy(:, t)] = max(S, [], 2);
end
end
```
此代码实现了简单的演化博弈模型,其中:
- `n`:玩家的数量
- `T`:回合数
- `S`:得分矩阵(n x n)
- `P`:策略分布的初始概率(n x 1)
输出:
- `strategy`:每个玩家在每回合中采用的策略
- `scores`:每个玩家在每回合中获得的得分
希望这些代码能帮助您。如果您需要更详细的解释,请告诉我。
