votca::xtp::ThinningWaitingTime Class Reference

Thinning (Lewis-Shedler) for any rates with time-independent upper bounds B_e >= w_e(t): candidate events at the constant rate sum_e B_e, destination proposed with probability B_e / sum B, accepted with probability w_e(t)/B_e. Exact for every time dependence; the cost grows with the ratio bound / mean rate. More...
