I coding in julia using JuMP of Juliopt. I would like to know how to print the solve progress using CbcSolver?
I already used the log level parameter: m = Model(solver = CbcSolver(log=1))
it works and you can choose between 0 to 3, higher more details.
but my problem is that the log level only prints after the solver finish, i already put the the time limit parameter "sec" but when it is set for higher values never stops and i don't know why!!
m = Model(solver = CbcSolver(sec=90,log=1))
I was going to try callbacks but Cbc does not support callback.
I am positive that there is a way to print because when i use the opensolver in excel a set Cbc to solve it shows the progress.I just dont know how to do this!!
