Fractal image compression is a method to compress images, which significantly reduces the storage keep data of using partial iterated function systems. In this work, we generalize classical fractal graph-directed case.

we present a matching and lp based heuristic algorithm that decides graph non-hamiltonicity. each of the n! hamilton cycles in a complete directed graph on n + 1 vertices corresponds with each of the n! n-permutation matrices p, such that pu,i = 1 if and only if the ith arc in a cycle enters vertex u, starting and ending at vertex n + 1. a graph instance (g) is initially coded as exclusion set ...

let $g=(v‎, ‎e)$ be a graph with $p$ vertices and $q$ edges‎. ‎an emph{acyclic‎ ‎graphoidal cover} of $g$ is a collection $psi$ of paths in $g$‎ ‎which are internally-disjoint and cover each edge of the graph‎ ‎exactly once‎. ‎let $f‎: ‎vrightarrow {1‎, ‎2‎, ‎ldots‎, ‎p}$ be a bijective‎ ‎labeling of the vertices of $g$‎. ‎let $uparrow!g_f$ be the‎ ‎directed graph obtained by orienting the...

Knowledge generated from appliances usage data can be used for personalizing and reducing the number of user interactions. Appliances such as Washing Machines (WM) are capable storing settings selected by user, during operation. Before operation a WM, has to enable options these preferred mode We have proposed Device Interaction Graph solution that automatically recommends auto-completes user’s...
