### Improving MSE as fitness function for a genetic algorithm

I am implementing an autoencoder neural network in matlab, the weights of which are being optimised by a genetic algorithm. At the moment I am working on the first layer, trying to get an improved ...

### Bit distance and disruption [duplicate]

Earlier, I asked a question defining disruption in Genetic Algorithms. Given that definition, I'm still confused on how to answer the following question. True or false? For 1-point and 2-point ...

### Disruption in the context of Genetic Algorithms

I'm trying to do a homework problem which references "disruption" in Genetic Algorithms. True or false? For 1-point and 2-point crossover, the schemata which have bits that are close ...

### Progressive discrete multifunction optimization

I have a set of functions $F$. The functions effectively take a set $S$ that is always a subset of a global set of all possible values $G$, where $|G|>1000$. (alternatively, they could take a $|G|$...

### How to use Sigma Scaling in a genetic algorithm

I have a genetic algorithm in Java and I'm testing new types of selections. For my tests I'm using the De Jong Half Sphere, my fitness function is $x^2 + y^2$. The selection method used is Sigma ...

### How to stop genetic algorithm population converging to a single value

I've written a genetic algorithm (GA) that solves a 7-dimensional optimisation problem. All seven variables are floating point numbers. The problem is that the entire population seems to converge to ...

### Selection of parameters for genetic algorithm

How can one select the proper number of parameters for a genetic algorithm to model a given system? For example, say you want to optimize production of cars, and you have 1,000 measurements of hourly ...

### Genetic algorithm fitness function [closed]

I'm trying to write some little code (POC for the selection/mutation operators) that uses a genetic algorithm to solve a global maximum for a function. ...

### Genetic algorithm: What is the expected number of strings that are explored?

My question concerns genetic algorithm searching along bit strings. Given: $N$ = population size $l$ = length of bit strings $p_c$ = probability that a single crossover occur (double crossover never ...

### A genetic algorithm modified for a specific problem

I have a problem whose solution can be written as a binary string with a given length $N$, where $N$ is a given parameter. Standard GA works well on this problem. From runs of small values $N$, I ...

### Is there a crossover operator to cross sections of specific phenotype genes?

For example, I've a chromosome with 10 genes, the first 5 genes represent a specific property of phenotype and the last 5 genes represent another property of phenotype. So, I need a crossover ...

### Something I don't understand about Genetic Algorithms

I've had a bit of experience programming Neural networks but I am fairly new with genetic algorithms (I'm only 17). I have a major issue that I can't understand. If a child get's one chromatid from ...

### Evolutionary algorithm for the Physical Travelling Salesman Problem

I want to solve the Physical Travelling Salesman Problem using an evolutionary algorithm. The objective of the PTSP is to visit the maximum number of waypoints of the map in the minimum number of ...
