I'm trying to obtain the time to find all integer solutions. What I need is that XPRES prints out or anyway returns the time elapsed since the execution started every time a new integer solution is found. Is there a way to do that? I know already of the gettime approach, but that seems to work only to obtain the whole time of execution (i.e. from the beginning until the execution stops becuase it has found the optimal solution). What I need is different since I need to have the time needed to find every solution from the beginning, not just the total time of execution.
Thank you very much for your help
