add2.java

代码是一个分类器的实现,其中使用了部分weka的源代码。可以将项目导入eclipse运行

package com.lqy.GEP;

import weka.core.EuclideanDistance;
import weka.core.Instance;

public class ADD2 implements Symbol{//二元加法
	public boolean isTerminal(){
		return false;
	}
	public String getName(){
		return "+";
	}
	public double eval(double[] argS){
		int tempArity=this.getArity();
		if(argS.length<tempArity)
			return 0;
		double tempSum=0;
		for(int i=0;i<tempArity;i++)
			tempSum+=argS[i];
		return tempSum;
	}
	public int getArity(){
		return 2;
	}
	public int getParameterSize(){
		return 0;
	}
	public void setParameters(double[] argD){}
	public double getValue(EuclideanMeasure argD,Instance argIA,Instance argIB){
		return 0;
	}
	public double getValue(double[] argD){
		return 0;
	}
	public double getValue(double[] argD,Instance argIA,Instance argIB){
		return 0;
	}
}
