function [parent] = binaryMutate(parent,bounds,Ops)
% Binary mutation changes each of the bits of the parent
% based on the probability of mutation
%
% function [newSol] = binaryMutate(parent,bounds,Ops)
% parent  - the first parent ( [solution string function value] )
% bounds  - the bounds matrix for the solution space
% Ops     - Options for binaryMutation [gen prob_of_mutation]

numVar = size(parent,2)-1; 		% Get the number of variables 
% Pick a variable to mutate randomly from 1-number of vars
rN=rand(1,numVar)<pm;
