The post-Newtonian hydrodynamic equations for a non-perfect fluid are developed within the framework of Boltzmann equation. components energy–momentum tensor determined by considering relativistic Eckart decomposition viscous and heat conducting fluid. From Grad distribution function its expression is derived. mass density, mass-energy density momentum from transfer equation Grad’s function. In...

The equilibrium optimizer (EO) is a novel physics-based meta-heuristic optimization algorithm that inspired by estimating dynamics and states in controlled volume mass balance models. As stochastic algorithm, EO inevitably produces duplicated solutions, which wasteful of valuable evaluation opportunities. In addition, an excessive number solutions can increase the risk getting trapped local opt...
