1 PSO – Rosenbrock(10) for Example

2 User can use methods Init() - polymorphism –Init(int PopulationSize, int VariableDimension, double VariableLowerbound, double VariableUpperbound, string RepeatableOption) –Init(int PopulationSize, int VariableDimension, double[] VariableLowerbound, double[] VariableUpperbound, string RepeatableOption) Run() –Run(int Iteration) Update() - polymorphism –Update(string FirstGuidingPoint, string SecondGuidingPoint) –Update(string FirstGuidingPoint, string SecondGuidingPoint, string ThirdGuidingPoint)

3 User can override attributes and methods Attribute (lSize default is 3 and RefSet default is 10) –public override int lSize { get { return 5; } } –public override int RefSetSize { get { return 20; }} Method –public override double Fitness(double[] sol)

4 PSOOption Class User used PSOOption when having no idea to determine problem options or strategy options. PSOOption –RepeatableOption Repeatable, Nonrepeatable –FirstGuidingPoint Pbest, Lbest, Gbest, Random, RefSet –SecondGuidingPoint Pbest, Lbest, Gbest, Random, RefSet –ThirdGuidingPoint Pbest, Lbest, Gbest, Random, RefSet

6 Step 1 and 2 using System; using System.Collections.Generic; using System.Text; using Metaheuristic; namespace Testing { class Rosenbrock : PSO { } Step 1: Include Metaheuristic. Step2: Problem class must inherit PSO.

7 Step 3 and 4 using … namespace Testing { class Rosenbrock : PSO { static void Main(string[] args) { Rosenbrock bird = new Rosenbrock(); } public override double Fitness(double[] pos) { double fitness = 0; for (int j = 0; j < pos.Length - 1; j++) fitness = fitness * Math.Pow(pos[j + 1] - Math.Pow(pos[j], 2), 2) + Math.Pow(pos[j] - 1, 2); return fitness; } Step 3: Creating object. Step 4: To override Fitness function.

8 Step 5 using … namespace Testing { class Rosenbrock : PSO { double[] Low = new double[10] { -10, -10, …, -10 }; double[] Up = new double[10] { 10, 10, …, 10 }; static void Main(string[] args) { Rosenbrock bird = new Rosenbrock(); bird.Init(40, 10, -10, 10, PSOOption.RepeatableOption.Repeatable); //bird.Init(40, 10, Low, Up, “Repeatable”); } public override double Fitness(double[] pos)… } User can use arrays to input lower bound and upper bound for each variable. Polymorphism RepeatableOption has two expressions of PSOOption and string.

9 Step 6 – Simple Call using … namespace Testing { class Rosenbrock : PSO { static void Main(string[] args) { Rosenbrock bird = new Rosenbrock(); bird.Init(40, 10, -10, 10, “Repeatable”); bird.Run(4000); } public override double Fitness(double[] pos)… } Default is Constriction Factor PSO

10 Step 6 – Advanced Call using … namespace Testing { class Rosenbrock : PSO { static void Main(string[] args) { //public override int lSize { get { return 5; } } //public override int RefSetSize { get { return 20; }} Rosenbrock bird = new Rosenbrock(); bird.Init(40, 10, -10, 10, “Repeatable”); for (int iter = 1; iter <= 4000; iter++) bird.Update(); //bird.Update(“Pbest”, PSOOption.SecondGuidingPoint.Lbest); //bird.Update(PSOOption.FirstGuidingPoint.Pbest, “Gbest", “RefSet"); } public override double Fitness(double[] pos)… } Polymorphism FirstGuidingPoint, SecondGuidingPoint and ThirdGuidingPoint have two expressions of PSOOption and string. If user used Lbest or RefSet as guiding point, user would override lSize and RefSetSize.

11 User requirement 1 for Rosenbrock(10) User requirement. –PopulationSize = 40, VariableDimension = 10, VariableLowerbound = -10, VariableUpperbound = 10, RepeatableOption = “Repeatable”. –Iteration = –Using two guiding points of pbest and gbest.
