Multipoint and Multi-Objective Aerodynamic Shape Optimization
A gradient-based Newton–Krylov algorithm is presented for the aerodynamic shape optimization of singleand multi-element airfoil configurations. The flow is governed by the compressible Navier–Stokes equations in conjunction with a one-equation transport turbulence model. The preconditioned generalized minimal residual method is applied to solve the discrete-adjoint equation, which leads to a fa...
متن کاملmulti-objective optimization of hydropwoer multi-objective optimization of hydropower reservoirs operation based on the pattern of PAB markets
In recent years, the structure of the electricity industry has undergone a change and since November 2003, when the electricity market of the country was launched, its monopoly structure has become a competitive structure. In this market, the forecast of electricity prices is not only necessary in pricing but also plays an important role in finding the optimal operation strategy by the power pl...

Evolutionary Algorithms Applied to Multi-Objective Aerodynamic Shape Optimization
Optimization problems in many industrial applications are very hard to solve. Many examples of them can be found in the design of aeronautical systems. In this field, the designer is frequently faced with the problem of considering not only a single design objective, but several of them, i.e., the designer needs to solve a Multi-Objective Optimization Problem (MOP). In aeronautical systems desi...
متن کاملMOEICA: Enhanced multi-objective optimization based on imperialist competitive algorithm
In this paper, a multi-objective enhanced imperialist competitive algorithm (MOEICA) is presented. The main structures of the original ICA are employed while some novel approaches are also developed. Other than the non-dominated sorting and crowding distance methods which are used as the main tools for comparing and ranking solutions, an auxiliary comparison approach called fuzzy possession is ...
