Hello, I already asked for the following problem:
According to the variables defined in our model (x,y,z,k), I obtained the following solutions : 1,1,2,3 1,1,5,6 1,1,7,9 1.1,8,8 I am interested to the values of the two variable x and y, so I want to avoid the enumeration of the three last solution in order to display just the first solution. I got the following response: One way to do it is as follows: - You create a space s that only has a brancher for x and y - You create a search engine e1 for s and find a solution, say s1 - You post a brancher in s1 for z and k. - You create a search engine e2 for s and find just a single solution! - You can then also get more solutions from e1 and repeat the previous two steps. Thank you for the solution, it works very well, but I have an other problem which is the enumeration order of the variables x, y, z and k. I must begin the branching from the variables z and k, then x, y (In this way, Gecode enumerates quickly the solutions but for the first order "x,y,z,k", it takes about 30 minutes to enumerate the first solution). Is there an other solution? Thank you. ----- Amina _______________________________________________ Gecode users mailing list users@gecode.org https://www.gecode.org/mailman/listinfo/gecode-users
