The problem of finding paths in temporal graphs has been recently considered due to its many applications. In this paper we consider a variant the that, given vertex-colored graph, asks for path whose vertices have distinct colors and include maximum number colors. We study approximation complexity provide an inapproximability lower bound. Then present heuristic experimental evaluation our heur...

Edge-fuzzy graphs constitute an essential modeling paradigm across a broad spectrum of domains ranging from artificial intelligence to computational neuroscience and social network analysis. Under this model, fundamental graph properties such as edge length and graph diameter become stochastic and as such they are consequently expressed in probabilistic terms. Thus, algorithms for fuzzy graph a...

In this paper, a fuzzy engineering economic decision model is derived to evaluate the investment feasibility of wind generation project. A straightforward vertex parameters’ fuzzy mathematics operation using the function principle is derived as an alternative to the traditional extension principle, and is applied to evaluate a number of different economic decision indexes. Compared to the exten...

In this paper, we present our work on fuzzy modeling, and in particular an approach based on the integration of the uncertain theories in the formalism of multimodeling and simulation with discrete events DEVS. The goal of this approach is to help the expert of a eld to specify in a simple way the behavior of a complex system with parameters badly de ned, fuzzy, etc. This approach can be employ...
