MATLAB: How to show convergence graph with intlinprog/branch and bound

2016abranch and boundcovergencegraphintlinprogMATLABmilpoptimization

I am working on a MILP problem on MATLAB 2016a that uses intlinprog to find the optimal solution. The solver always goes into the branch and bound stage to find the solution. I would like to know how would I show the convergence of the solution to the optimum value with a graph? (Perhaps an in-built MATLAB function in the options)? Thank you.

You can use the optimplotmilp plotfunction to view convergence. See intlinprog output functions and plot functions.

You can use the savemilpsolutions output function to collect the integer-feasible points that intlinprog found during its branch-and-bound search. See intlinprog output functions and plot functions.

'threshold',ceil(0.3*max(H(:)))

are not sensible arguments for the code you posted. They may be for the Matlab builtin, but this one requires a number for threshold and a 2-element vector for the neighbourhood.

If you don't know what neighbourhood you want then it creates one by default so you can just call it as:

P  = houghpeaks(H,5,ceil(0.3*max(H(:))));

in that case.

Matlab builtin functions regularly use the { property, value } pair approach for input arguments after the first few, but 3rd party code tends not to and this code just expects you to give the inputs in exactly the order they are specified - it does not support { property, value } pairs like that above.
