| Popis: | Summary: The paper deals with application of the ortho-diagonal (O-D) method of finding the nondominated sets of solutions and evaluations for dicrete polyoptimization problems. First, the O-D method is modified for finding minimum of a scalar function. The monotonicity property of a vector objective function is used by the O-D method for consecutive finding of \(j\)th-criterion partial nondominated sets, \(j\in \{1,2,\dots, J\}\). To find the nondominated evaluations sets, the discrete neighbourhoods \(S\) of the point \({\mathbf x}_i\) are investigated starting from the solution \({\mathbf x}^*_1\) which minimizes the first objective function. In this way we are able to determine the consecutive nondominated solutions \({\mathbf x}^k_{ND}\). The accuracy of solution and CPU time depend on the definition discrete neighbourhoods \(S\) of the point \({\mathbf x}_i\) in the design space. The he algorithm of the O-D method is applied to solve the discrete polyoptimization of a hall with spatial grid structure. |
