can you write c code for the alpha beta algorithm
And here the code + answer:
Code: Select all
#include <limits.h>
int alpha_beta(int depth, int alpha, int beta, int maximizingPlayer)
{
if (depth == 0 || game_over())
{
return evaluate_position();
}
if (maximizingPlayer)
{
int bestValue = INT_MIN;
for (int i = 0; i < number_of_children(); ++i)
{
int value = alpha_beta(depth - 1, alpha, beta, false);
bestValue = max(bestValue, value);
alpha = max(alpha, value);
if (beta <= alpha)
{
break;
}
}
return bestValue;
}
else
{
int bestValue = INT_MAX;
for (int i = 0; i < number_of_children(); ++i)
{
int value = alpha_beta(depth - 1, alpha, beta, true);
bestValue = min(bestValue, value);
beta = min(beta, value);
if (beta <= alpha)
{
break;
}
}
return bestValue;
}
}
