Dear Jaromił, Thanks a lot for your help. Authors of that paper used C programming language with a heuristics to find solutions. They got 4 solutions using 6 cores within 1 month. I tried to solv...

Dear Jaromił Thanks a lot. What exactly do you mean by being not able to solve but the problem becomes faster? Really sorry for not writing clearly. If we remove constraints C1, D1 and C2, we can s...

Dear Jaromił, Thank you so much for your help. If we include another constraint v0 + v1 + v2 + v3 + v4 + v5 + v6 + v7 + v8 + v9 + v10 + v11 + v12 + v13 + v14 + v15 + v16 + v17 + v18 + v19 + v20 ...

Hi, Thank you so much for your comments. I see if I take 2*113=226 constraints, it gives the solution very fast. But can not solve 228 constraints. Regards, Santanu

No optimization function
CompletedMy interest is to find only one common solution for a binary integer problem. My problems are like this: Subject ToA1 : a0 + 9 a1 + 5 a2  2 a3 >= 10A2 : a0 + 9 a1 + 5 a2  2 a3 <= 20A3 : 2 a0 + ...

How to to define multivariate polynomials
AnsweredHi, Is it possible to define multivariate polynomials in Gurobi? I have y1=a1 l1+a2 l2 +a3 l3, y2= a1 l4 + a2 l5 + a3 l6, y3= a1 l7 + a2 l8 + a3 l9 where y1, y2, y3, a1, a2, a3 are binary variable...
