In this study, we used a particle swarm optimization (PSO) algorithm to address a variation of the non-deterministic polynomial-time NP-hard traveling tournament problem, which determines the optimal schedule for a double round-robin tournament, for an even number of teams, to minimize the number of trips taken.Our proposed algorithm iteratively ex
In the studies of groundwater flow and solute transport, many efforts have been made to estimate hydrogeological parameters through physical-distance based localization schemes of ensemble assimilation approaches.However, these methods are unavailable when Support there are no physical distances between parameters and observations.To avoid this lim
It has often been argued that countries that produce natural resources mobilize less non-resource tax revenues than other countries.In this paper, we exploit Hoods the exogenous variation in the timing of giant oilfield discoveries to estimate the causal impact of natural resources on taxation.The timing of giant oilfield discoveries is arguably ex
The specific features of the control of the production process during the commissioning (the start-up and adjustment) of a thermal power plant are considered.The composition of the time spent on start-up and adjustment of modern high-tech equipment and engineering systems is considered.In the article a mathematical relationship between the duration
