How do I write a Genetic algorithm code for multiple choice questions?

12 Apr 2015 by Peter Leow

Understanding the mechanism of GA is already hard, not to mention trying to interpret other people's code that implements it. That is even harder if you never code before. Come back to the GA, you can create a model like this:1. Represent each potential solution by a 40 gene-chromosome,...

Genetic algorithm. A population contains chromosomes, that don't perform conditions. What should I do with?

3 Apr 2015 by Member 11418478

I'm working on Transport Salesman Problem solution with a Genetic Algorithm.Some chromosomes are contain the shortest way, but they still aren't appropriate. For example, a salesman must get to the A city at 6.00 pm, but using the solution of a chromosome he'll get there at 7.00 pm. Thus,...

Genetic algorithm. A population contains chromosomes, that don't perform conditions. What should I do with?

3 Apr 2015 by Peter Leow

It is a matter of how you want to handle the various constraints in your GA model. There can be 2 types of constraints: 1. Hard Constraints: Requirements that must be met. You may discard such solutions or repair them by orchestrating a mutation.2. Soft Constraints: Requirements that can...

Finding source code on the internet is not a good way to do this: particularly if you have no idea what the code you have found does or how it does it.Seriously, you need to learn the subject and try it for yourself - you won't learn much (if anything) by "finding code" and trying to get us...

Pathfinding in genetic algorithms and game programming

17 Oct 2016 by F-ES Sitecore

You probably mean "generic", not "genetic". I don't think it matters what you call it, it probably doesn't have a fixed name as there are different types of algorithm you can use to solve the problem. Look at "the travelling salesman problem" as well, you'll see a lot of commonality between...

Pathfinding in genetic algorithms and game programming

A 'pathfinding algorithm' is what the title says: just an algorithm able to find a somehow optimized path in a given scenario.Since this can be useful in game development then path finding algorithms are often used in such area (that doesn't mean it is a game programming topic). Genetic...

Can I get some help with a java array equivalent in C#?

18 Mar 2017 by takatok

The code is functionally equivalent. You say that your problem is that qc[0] is often 0 and its causing problems. With your code your taking some C_dat array and converting every EVEN index of that array (0,2,4,etc) into a double and adding it to qc[0]. So the only reason qc[0] should equal...

I order to make operations (e.g. compare rows) with your data, you should store it (your code overwrites the same array). Try, as a starting point #include #include #define SIZE 20 void init(int a[SIZE][SIZE], int sum[SIZE]); void dump(int a[SIZE][SIZE], int sum[SIZE]); ...

Perform crossover operation on AST in genetic programming

So in general when you perform a crossover in GA, you directly flip a random section in the "genome", with the corresponding section in the other parent, and mutate it based on the mutation rate.Consider the sequences below:0100 1000 0001 10110010 0110 1101 1111A crossover without...
