我试图学习关于布谷鸟搜索算法的概念。老实说，我正在使用java源代码学习布谷鸟搜索。我们知道杜鹃搜索使用征收分布进行随机游走。我有java源代码inslements布谷鸟搜索优化，但我怀疑使用征收分发的源代码。任何人都可以帮助我使用征税分配检查我的源代码吗？。
这是实现随机漫步的方法..
public CSSolution randomWalk (OptimizationProblem prob, String distribution) {
int n = prob.getNumVar(); //2
// creates a neighborhood of size 1 times the scaling factor
double distanceSquared = Math.pow(rand.nextDouble() *
prob.getScalingFactor(),2);
System.out.println("distance Squared : "+distanceSquared);
// creates an ArrayList from 0 to n-1 (for indexing purposes only)
ArrayList<Integer> varIndices = new ArrayList<Integer>(n);
for (int i = 0; i < n; i++) {
varIndices.add(i, i);
}
ArrayList<Double> vars = this.getVars();
CSSolution newSol = new CSSolution(this.numVars);
newSol.initializeWithNull();
ArrayList<Double> newVars = newSol.getVars();
for (int i = 0; i < n; i++) {
/* Chooses a random variable index from the indices
* of the remaining/unwalked variables. */
int index = rand.nextInt(varIndices.size());
// Finds the variable value that this index corresponds to.
int varIndex = varIndices.get(index);
// System.out.println("varIndicesSize:"+varIndices.size()+" index: "+index+" varIndex: "+varIndex);
double curVar = vars.get(varIndex);
// use correct distribution to generate random double [0,1)
double r;
if (distribution == "weibull"){
r = weibull.random(1.5, 1, new uniform());
}
else if(distribution == "levy"){
r = 0.0;
}
else
r = rand.nextDouble();
// alters this variable coefficient by adding a random step between (-distance,distance)
double distance = Math.sqrt(distanceSquared);
System.out.println("distance : "+distance+" distance Squared : "+distanceSquared);
double varStep = r*distance*2-distance;
double newVar = curVar + varStep;
// System.out.println("x"+varIndex+" : "+curVar+" to "+newVar);
newVars.set(varIndex, newVar);
// removes the variable that has already been visited
varIndices.remove(index);
// updates distance for next for loop
distanceSquared -= Math.pow(varStep, 2);
}
// System.out.println("");
return newSol;
