### Examples

    n = 100
    k = 20
    theta = 0.5
    pp <- networkSimulation(n,k,theta)
    moduleid <- pp[[3]]
    ## use default parameters here
    x <- CGPFixSS(pp[[1]],pp[[2]],rep(1/n,n))
    predictedid<-which(x[[2]]!=0)
    recall <- length(intersect(predictedid,moduleid))/length(moduleid)
    precise <- length(intersect(predictedid,moduleid))/length(predictedid)
    Fscore <- (2*precise*recall/(precise+recall))
