How to create a good fitness function?
In genetic algorithms, a function called "fitness" (or "evaluation") function is used to determine the "fitness" of the chromosomes. Creating a good fitness function is one of the challenging tasks in genetic algorithms. How would you create a good…

Why does the fitness of my neural network to play tic-tac-toe keep oscillating?
I wrote a simple feed-forward neural network that plays tic-tac-toe:
9 neurons in input layers: 1 - my sign, -1 - opponent's sign, 0 - empty;
9 neurons in hidden layer: value calculated using ReLU;
9 neurons in output layer: value calculated using…

How to improve the performance of my model trained with NEAT for a drone to learn how to fly?
I am working on a project in which a drone needs to learn how to fly. I am using NEAT.
For the first experiment, I want the drone to learn how to hover inside a $3 \times 3 \times 3$ meters box. My input is 6 sensors for each direction. The output…

How to design a fitness function for the 8-queens problem?
In evolutionary computation and, in particular, in the context of genetic algorithms, there is the concept of a fitness function. The better a state, the greater the value of the fitness function for that state.
What would be a good fitness function…

How do I design a fitness function that weighs the importance of eating food?
Summary:
I am teaching bots to pick food on a playing field. Some food is poisonous and some is good.
Food Details:
Poisonous food subtracts score points and good food adds.
Food points vary based on its size.
There is about 9:1 ratio of poisonous…

How to design a fitness function for a problem where there are 2 objectives?
I am told to express a fitness function for a question I have been presented. I am unsure how I would express the function. In words, what I have written down makes sense but turning this into a mathematical formula is proving a bit difficult. My…
