I am currently decoding a cuckoo search program, I don't understand why there is a need for Adding Values:

% divide a (hyper)circle to 'numRadiuses' segments

% This is to search all over the current habitat

angles = linspace(0,2*pi,numRadiuses); % in Radians

newParams = [];

for cnt = 1:numRadiuses

addingValue = zeros(1,npar);

for iii = 1:npar

randNum = floor(2*rand)+1;

addingValue(iii) = (-1)^randNum * tmpRadiuses(cnt)*cos(angles(cnt)) + tmpRadiuses(cnt)*sin(angles(cnt));

end

newParams = [newParams; params + addingValue ];

end

What is the relation between cuckoo eggs and number of variables?
