Exact and safe structural analysis and design under various loadings is an important issue, which have engaged engineers for a long time. Till now, building design codes have suggested three main methods for seismic analysis of structures, which consist of: Static analysis, Pseudo-dynamic response spectrum analysis and Time history analysis. The first two methods are too approximate, especially in irregular structures which demand exact 3d analyses. The most reliable method is Time history method. With advance of computational tools, engineers tend toward using more reliable analysis methods and using old fashioned rough methods is becoming less popular. One of the issues, which is important... 

Motivated by the fact of lack of infra-structure in multi-hop wireless networks, there is a controversial issue of assurance in protocols execution. Due to dynamic structure of these networks, local information should be considered for implementing related algorithms implementation. Selecting logical neighbors, named topology control, is one of these algorithms which have to take sanctity of the execution into consideration. To cope with these issues it can be beneficial to explore algorithm design problem in view of independent and rational agents. In other words, in investigating topology control algorithms in the presence of independent nodes, several contradictory problems were observed...
