Dear Yushazaziah Yunos

There is a difference between object function and fitness function

The function of fitness is always an incremental function while the target object may be decreasing or incremental

In the object function incremental there is no problem

the object function equal to the fitness function

Obj.fun=F.F

But if the object function incremental there is a problem, and to solve this issue if the objective function is decreasing, the solution must be as show

Obj.fun= 1/(1+FF)

In general, there is no difference between objective function and fitness function. In the context of GA, the "fitness" of an individual is calculated using the objective function.

Hi. Fitness value and objective function value are same.

Thank you all for the answers

Hi,

The two functions are found differently, but have the same meaning.

For me Both fitness and objectif functions are the same.

ye at first i think they are a same thing but then the solutions for GA are ranked by their fitness. So how the fitness is calculated? i think Mr Omar Hazem has answered the question. Thank you all

The objective functions belong to the optimizations of static solution universes, while the fitness functions pertain to problems with variable solution universes and are used to guide the algorithm towards convergence zones

Artura Benito Rodriguez, thank you for the answer.
