示例1: add_one_state

void EnsembleGenerator::add_one_state(const Ensemble& init_ensemble,
                                      Ensemble& new_ensemble) {

  std::priority_queue<boost::tuple<double, int, int>,
                      Vector<boost::tuple<double, int, int> >,
                      Comparator> bestK;

  // iterate over all init MultiStateModels and try to add a new state to each
  for(unsigned int i=0; i<init_ensemble.size(); i++) {
    unsigned int first_to_search = init_ensemble[i].get_last_state()+1;
    if(first_to_search<N_) {

      if(i>0 && i%100==0 && !bestK.empty()) {
        double curr_bestK_score = boost::get<0>(bestK.top());
        std::cout << "Extending ensemble: " << i << " out of "
                  << init_ensemble.size() << " last best "
                  << curr_bestK_score << std::endl;
      }

      MultiStateModel new_model(init_ensemble[i]);
      new_model.add_state(first_to_search);

      // try all possible additions of a new state
      for(unsigned int j=first_to_search; j<N_; j++) {
        new_model.replace_last_state(j);
        double curr_score = get_score(new_model);
        if(curr_score < 0.0) continue; // invalid model
        // add to bestK
        if(bestK.size() <= K_ || curr_score < boost::get<0>(bestK.top())) {
          bestK.push(boost::make_tuple(curr_score, i, j));
          if(bestK.size() > K_) bestK.pop();
        }
      }

  // save best scoring

    index--;
    bestK.pop();
