Genetic Algorithm Implementation in ns2

Genetic Algorithm is designed to simulate processes in natural systems. Over a consecutive generation, GA stimulates the survival of the fittest among individuals. GA is also a part of evolutionary computing. We guide research scholars for genetic algorithm implementation in ns2 simulator with source code.

Basic Operators in GA

   After the initial population, the algorithms define the following functions

• Selection.
• Crossover.
• And also Mutation.

   Get to know about the basic operator, applications, and benefits of genetic algorithm projects. Implement genetic algorithm in ns2 with guidance from industry experts for an affordable cost.

Applications of GA

• Airlines Revenue Management.
• Artificial creativity.
• Biology and also computational chemistry.
• Chemical kinetics.
• Computer architecture.
• Clustering.
• Electronic circuit design.
• Economics.
• Image processing.
• Mechanical engineering.

Benefits of GA

• GA solves the optimization problem.
• Solves problems with multiple solutions.
• Its execution technique is not dependent on the error surface.
• A structural genetic algorithm gives the possibility to solve the solution structure.
• The GA method is very easy to understand.
• Easily transferred to existing simulations and also models.

Genetic Algorithm Implementation in ns2 helps to solve out

• Multi-dimensional.
• Non-differential.
• Non-continuous.
• And also in Non-parametrical problems.
