COIN-OR Branch-and-Cut solver
The latest 59067a1 Cbc.sln in master for v16 (https://github.com/coin-or/Cbc/blob/master/MSVisualStudio/v16/Cbc.sln) fails to load libCgl, libClp, libCoinUtils, libOsi, etc. in Visual Studio 2019 because Cbc.sln refers to a configuration "ReleaseParallel" that is...
Hello I would like to understand whether cbc solver uses Revised simplex method to solve linear programming problem and uses Branch and bound algorithm to solve MIP problems. How to...
i hava see the example file `CInterfaceTest.c` but the example was too easy model.. i have confused by the param which called `start[]` ``` /* Simple knapsack problem Maximize 5x[1]...
when I am trying to build parallel CBC, I came up with the problem of abcState_ problem on line 1954. int abcState_; #define CLP_ABC_WANTED 1 #define CLP_ABC_WANTED_PARALLEL 2 #define CLP_ABC_FULL_DONE...
I have a relatively large LP (100k+ variables) that I have successfully solved with CBC numerous times. However, when I convert one of the variables to a binary or integer,...
like this https://web.cs.ucdavis.edu/~bmoazzez/CalSim_MILP_Solvers_files/jCbcManual.pdf still works? or update follow plan?
I'm trying to solve a family of IP instances where I know that the all zero solution is feasible. Since cbc 2.10.0 does not find a feasible solution to some...
I found a minor bug in the Cbc_isProvenInfeasible() and in the Cbc_isProvenOptimal(). If I try to solve a model, the functions work correctly, but if I add new constraints that...
I am reading a problem where the LP relaxation is also integer optimal. clp solves the problem in ~12 s. CPLEX solves the whole problem in several seconds. CBC finds...
