我想使用这个 q-learning(强化学习)代码。看起来代码是正确的,但我收到错误,我不知道为什么:
function q=ReinforcementLearning
clc;
format short;
format compact;
int state=0;
R= [-inf,-inf,-inf,-inf, 0,-inf;
-inf,-inf,-inf, 0,-inf, 100;
-inf,-inf,-inf, 0,-inf,-inf;
-inf, 0, 0,-inf, 0,-inf;
0,-inf,-inf, 0,-inf, 100;
-inf, 0,-inf,-inf, 0, 100];
gamma=0.8;
q=zero(size(R));
q1=one(size(R))*inf;
count=0;
for episode = 0:20000;
y=randperm(size(R,1));
state=y(1);
x=find(R(state,:)>=0);
if size(x,1)>0,
x1=RandomPermutation(x);
x1=x1(1);
end
qMax=max(q,[],2);
q(state,x1)=R(state,x1)+ gamma* qMax(x1);
int state=x1;
if sum(sum(abs(q1-q)))<0.0001 && sum(sum(q>0))
if count > 1000;
break
else
count=count+1;
end
else
q1=q;
count=0;
end
end
但我收到以下警告和错误:
enter code here
Warning: The method char/int will be removed in a
