示例1: accumulate
//NOTE: weights are not handled nicely.
//weight should be done carefully, not valid for DMC
//will add a function to MCWalkerConfiguration to track total weight
void EstimatorManager::accumulate(MCWalkerConfiguration& W)
{
BlockWeight += W.getActiveWalkers();
RealType norm=1.0/W.getGlobalNumWalkers();
for(int i=0; i< Estimators.size(); i++)
Estimators[i]->accumulate(W,W.begin(),W.end(),norm);
}示例2: accumulate
/** accumulate Local energies and collectables
* @param W ensemble
*/
void EstimatorManager::accumulate(MCWalkerConfiguration& W)
{
BlockWeight += W.getActiveWalkers();
RealType norm=1.0/W.getGlobalNumWalkers();
