=====================================

This is an exper. with "broken" neighbority ( similar to a ?bug which is in original Java version:

        function findNeighborWithBestAF()
        {
    	    var iB=0;
            var a = self.a;
    	    var f = p[a[0]].bAF;
    	    for( var i=1; i<aN; i++ ){
                if( p[a[i]].bAF > f ) {
    	    		iB = a[i];
    	    		f  = p[iB].bAF;
     	    	}
    	    }
    	    //bug?: return p[a[iB]];
    	    //return p[iB];
    	    return p[a[0]]; //"broken" neighbority
        }//findNeighborWithBestAF
