示例1: TrueRun
statscore_t RandomDirectionOptimizer::TrueRun(Point& P) const
{
statscore_t prevscore = P.GetScore();
// do specified number of random direction optimizations
unsigned int nrun = 0;
unsigned int nrun_no_change = 0;
for (; nrun_no_change < m_num_random_directions; nrun++, nrun_no_change++)
{
// choose a random direction in which to optimize
Point direction;
direction.Randomize();
//find the minimum on the line
statscore_t score = LineOptimize(P, direction, P);
if (verboselevel() > 4) {
cerr << "direction: " << direction << " => " << score;
cerr << " (" << (score-prevscore) << ")" << endl;
