示例1: setConvergence
// Use this method to update the statistics to account for the current
// population. This routine increments the generation counter and assumes that
// the population that gets passed is the current population.
// If we are supposed to flush the scores, then we dump them to the specified
// file. If no flushing frequency has been specified then we don't record.
void
GAStatistics::update(const GAPopulation & pop){
++curgen; // must do this first so no divide-by-zero
if(scoreFreq > 0 && (curgen % scoreFreq == 0)) setScore(pop);
if(Nscrs > 0 && nscrs >= Nscrs) flushScores();
maxever = (pop.max() > maxever) ? pop.max() : maxever;
minever = (pop.min() < minever) ? pop.min() : minever;
float tmpval;
tmpval = (on*(curgen-1) + pop.ave()) / curgen;
on = tmpval;
tmpval = (offmax*(curgen-1) + pop.max()) / curgen;
offmax = tmpval;
tmpval = (offmin*(curgen-1) + pop.min()) / curgen;
offmin = tmpval;
setConvergence((pop.order() == GAPopulation::HIGH_IS_BEST) ?
pop.max() : pop.min());
updateBestIndividual(pop);
numpeval = pop.nevals();
}示例2: memset
// Reset the GA's statistics based on the population. To do this right you
// should initialize the population before you pass it to this routine. If you
// don't, the stats will be based on a non-initialized population.
void
GAStatistics::reset(const GAPopulation & pop){
curgen = 0;
numsel = numcro = nummut = numrep = numeval = numpeval = 0;
memset(gen, 0, Nscrs*sizeof(int));
memset(aveScore, 0, Nscrs*sizeof(float));
memset(maxScore, 0, Nscrs*sizeof(float));
memset(minScore, 0, Nscrs*sizeof(float));
memset(devScore, 0, Nscrs*sizeof(float));
memset(divScore, 0, Nscrs*sizeof(float));
nscrs = 0;
setScore(pop);
if(Nscrs > 0) flushScores();
memset(cscore, 0, Nconv*sizeof(float));
nconv = 0; // should set to -1 then call setConv
cscore[0] =
((pop.order() == GAPopulation::HIGH_IS_BEST) ? pop.max() : pop.min());
// cscore[0] = pop.max();
// setConvergence(maxScore[0]);
updateBestIndividual(pop, gaTrue);
aveCur = aveInit = pop.ave();
maxCur = maxInit = maxever = pop.max();
minCur = minInit = minever = pop.min();
devCur = devInit = pop.dev();
divCur = divInit = ((dodiv == gaTrue) ? pop.div() : (float)-1.0);
on = pop.ave();
offmax = pop.max();
offmin = pop.min();
numpeval = pop.nevals();
for(int i=0; i<pop.size(); i++)
numeval += pop.individual(i).nevals();
