```Hey Andre,

why don't you just invert your fitness?

fitness best individual of generation 1: 5
fitness best individual of generation 2: 6
fitness best individual of generation 3: 4
fitness best individual of generation 4: 8

to

fitness best individual of generation 1: infinite - 5
fitness best individual of generation 2: infinite - 6
fitness best individual of generation 3: infinite - 4
fitness best individual of generation 4: infinite - 8

Now your max should be generation 3 because 4 is the lowest score.

minor and major can be easy inverted.

Greetings

Bojan

Betreff: Re: How to select individual with minor fitness

Normally the algorithm selects the individual with major value of fitness, for the example above will be selected the individual of generation 4:
fitness best individual of generation 1: 5
fitness best individual of generation 2: 6
fitness best individual of generation 3: 4
fitness best individual of generation 4: 8

but I want to select the individual that has the mijor/less value of fitness (in the case of example, the generation 3).

Thanks

I'm sorry, I don't know what you mean by "minor" and "major" fitnesses.
