How to include integer type variables in NGPM-1.4 program? Which is Matlab code for NSGA-II.

I need the code to modify the parameter allocation in NGPM-1.4 program.

The introduction for the second of those suggests that the first of those does not support integer constraints. It appears you are using this one already.

No constraint handling for that one.

That one is specifically Constrained NSGA-II but it appears to be restricted to 14 test cases.

For NGPM, use the routine nsgaopt() to generate an options structure. In that structure, set the vartype field to a vector of length the number of variables, with individual values being 1 if the variable is continuous and 2 if the value is integer. Set the lb and ub fields to the appropriate constraints; use -inf and +inf for unconstrained values.

Sir, I am using the following program. Please suggest the necessary modification in the following program. http://in.mathworks.com/matlabcentral/fileexchange/31166-ngpm-a-nsga-ii-program-in-matlab-v1-4?s_tid=srchtitle

I have attached the required file.

I already indicated the changes for NGPM: set the vartype and lb and ub fields of the generated nsgaopt structure and call ngsa2 with that structure as the options. No code change to NGPM is needed.
