Thanks a lot to all of them who answered my question.
Should I suppose that the answer to my question is negative, i.e. it is not possible to force GLPK to start searching from a particular point?
For your information, my project concerns the school timetabling problem. As I mentioned in my previous mail, I got a solution provided by Particle Swarm Optimization, but I do not know if this solution is optimal or not.
Any way, I found your answers very helpful. What I wrote in command prompt was :
glpsol --cuts --pcost --math my_model.mod --data my_data.dat --proxy 200 --mir --mipgap 0.2
The results were good and produced fast.
Nevertheless, I mast say that I have no idea about what --cuts, --pcost, --proxy, --mir and --mipgap 0.2 mean or stand for.
Could any one inform me in a few words about the meaning of all these? Or better, is there any text explaining all these?
Please note that the asked information is very crucial to me, as I shall be in a position to explain the way or the method I followed in order to discover these better solutions, compared with those found by Particle Swarm optimization.
Thanks for one more time
