    The extensive use of the Internet, for exchanging information, requesting and offering services make one to interact with unknown entities. Human use trust to facilitate interaction and accept the risk, when complete information is unavailable. In such situations, trust establishment mechanisms enable establishment of trust between unknown entities. Trust is...

    A Decade of Productive FPGA Utilization With Genetic Algorithms

    Genetic algorithms are one of the best ways to deal with the optimization problems. They are precisely suitable for mixed combinatorial problems. As genetic algorithms find the solution by producing more number of population generations based on selection, crossover, mutation etc., it can be further improved by exploiting computation power...
