It is an important decision-making problem for a miner in the blockchain networks if he/she participates mining so that earns reward by creating new block earlier than other miners. We formulate this as noncooperative game, because probability of depends not only on one's own available computational resources, but also those Through theoretical and numerical analyses, we show hysteresis phenome...

this paper deals with the product mix problem using the concept of theory of constraints (toc). theory of constraints is one of the most efficient approaches which have been applied to solve the product mix problem heuristically. although there are numerous heuristic and meta-heuristics to solve this problem, finding the optimal solution in a reasonable time is still a challenging issue. in thi...
