Aiming at the scheduling problem of underground mining equipment in shot mining, this paper proposes an improved cultural gene algorithm (MA). The global search applies the genetic algorithm, and some adjustments are made in its crossover and mutation operations; the local search uses the simulated annealing algorithm. The global search applies the genetic algorithm, and some adjustments are made in its crossover and mutation operations; the local search uses the simulated annealing algorithm, considering that the algorithm will have a certain probability to jump out of the optimal solution range, so on the basis of the original algorithm, the Gaussian function is replaced by the Cauchy function to avoid this problem. The algorithm is applied to the scenario of 5S15J for simulation experiments. After that, compared with the results of the genetic algorithm, it shows that the improved MA algorithm is obviously better in total time and total interval time, and can obtain high-quality solutions and an ideal cooperative scheduling strategy.

In this work, coherent modulation Terahertz communication link with pointing errors are analyzed for the Gamma-Gamma turbulence channels. The high-precision bit error rate and outage probability expressions for the Gamma-Gamma turbulent channel using coherent quadrature phase-shift keying signal are derived, and the bit error rate and outage probability are analyzed for its asymptotical property. The results show that our series error rate expression can accurately evaluate the system performance. It has high precision in estimating and predicting actual error rates.
