Hello All, I've been used the Genetic Algorithm in Scilab 5.4.1 (with the optim_ga macro). After a lot of tests, I would like to report a strange behaviour. That is, from the second time that I ran the algorithm, I always note a time increment to get the results. For example, to optimize a schedule problem with 40 tasks, at the first time the results could be given in 5 minutes, but from the second time it will be much more than 5 min. (This time is only a example, ok?!)
I also noted that when I close the Scilab environment and start it again, I can get my results, for example, in the same 5 minutes. (But, I always will need close and start to get time and results (in terms of quality) corrects.) So, my questions are: 1. What is happening with my Scilab? 2. Is that behaviour correct? 3. Somebody who works with optimization already had problems like this? Thanks in advance for attention! Best regards, Eduardo.
