acceptance ratio handling of the different Monte Carlo Moves types For each move type and each temperature average acceptence is determined. For each move is a weight (mv_weight) defined, which defines the probability to perform the move. We distinguish between moves performed on the exact potential (move on the master, energy on the energy worker) and NMC moves, which are performed on the worker using the approximate potential. The energies are calculated as usual on the energy worker with the exact potential. The move probabilities to perform a NMC is stored in the NMC move. The probilities of the single move types (performed with the approximate potential) are only compared within the NMC move

SUBROUTINE

add_mv_prob (move_types, prob_opt, mv_counter, acc_counter, subbox_counter, subbox_acc_counter)add the actual moves to the average probabilities

checks if the moves are possible

clear the statistics of accepting/rejection moves because worker statistics will be add seperatelly on masters counters

deallocating the module variables

routine pronts out the probabilities and sized for each type and temperature the output is divided into two parts the init, which is printed out at the beginning of the programm and .NOT.init which are the probabilites and counter printed out every print cycle

adaptation of acceptance probability of every kind of change/move and the overall acc prob, using the acceptance and rejectance information

initialization of the different moves, with sizes and probabilities

selects a move type related to the weighings and the entered rnd nr

add the actual moves to the average probabilities
