 Re: [gplab-users] crossover probability From: Sara Silva - 2008-07-02 13:48:35 ```Hi, Section 3.16 of the manual is dedicated to the initial operator probabilities, but you're right, the instructions are not very clear. The probability of occurrence of the genetic operators always adds to 1. If you want to use crossover and mutation, for example, then you should do: Reset params and name the operators to use: >> p=resetparams; >> p=setoperators(p,'crossover',2,2,'mutation',1,1); For fixed probabilities: >> p.operatorprobstype='fixed'; >> p.initialfixedprobs=[0.9 0.1]; For variable probabilities: >> p.operatorprobstype='variable'; >> p.initialvarprobs=[0.9 0.1]; But if you want to use only crossover, it doesn't really matter what settings you use, as the probability of crossover will always be 100%. There is an exception, however. If you set the reproduction rate to 0.1, for example, it means that in 10% of the cases an individual will be copied into the next generation, unchanged. In the other cases a genetic operator will be used to create new individuals, using the probabilities described above. I hope this helps, Sara Rosanny Sihombing wrote: > hi all, > > i'm having problem with adjusting the crossover probability. > if i wanna set my crossover probability to 90%, how can i do this? i have > read the manual, but i still couldn't understand how > > ```
