[Symphony] biobjective problems

[Papis Wongchaisuwat]

I would like to run bi-objective Set cover and Set pack problems. Attached files are some examples that I want to run. MCKP and these problems are quite different. I don't know how to apply MCKP or either use any other ways to run these problems.
Thank you,Papis

I tried MCKP (bicriteria knapsack problems) application and it works. I also want to run other bicriteria problems which I don't know how to do that.
