in this paper a network comprising alternative branching nodes with probabilistic outcomes is considered. in other words, network nodes are probabilistic with exclusive-or receiver and exclusive-or emitter. first, an analytical approach is proposed to simplify the structure of network. then, it is assumed that the duration of activities is positive trapezoidal fuzzy number (tfn). this paper com...

We describe CompleteSearch, an interactive search engine that offers the user a variety of complex features, which at first glance have little in common, yet are all provided via one and the same highly optimized core mechanism. This mechanism answers queries for what we call context-sensitive prefix search and completion: given a set of documents and a word range, compute all words from that r...

Ryjáček introduced a closure concept in claw-free graphs based on local completion at a locally connected vertex. He showed that the closure of a graph is the line graph of a triangle-free graph. Brousek and Holub gave an analogous closure concept of claw-free graphs, called the edge-closure, based on local completion at a locally connected edge. In this paper, it is shown that the edge-closure...
