A search algorithm with normal distribution (optimized dichotomy method)

Looking for a value in an ordered static table, the probability of its table is normally distributed, but the center of the data is not obtained in the midpoint of the data, how to get the optimal algorithm.    The code is as follows://Determine if in this interval function bool Check (int number) void callfunction (int min,int max) {int temp=0;//intermediate variable bool Flag=check (max);  while (flag) {Min=max; Max=2*min;    } while (Min<max) {temp= (Min+max)/2;  Flag=check (temp);  if (flag) {min=temp+1;  } else {max=temp-1; }} return 0;}
