exp.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 java.math.*;

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

public class EXP implements Symbol{
	public boolean isTerminal(){
		return false;
	}
	public String getName(){
		
		return "exp";
	}
	public double eval(double[] argS){
		return Math.exp(argS[0]);
		
	}
	public int getArity(){
		return 1;
	}
	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;
	}
}
