dynamic coloring of graph
در این پایان نامه رنگ آمیزی دینامیکی یک گراف را بیان و مطالعه می کنیم. یک –kرنگ آمیزی سره ی رأسی گراف g را رنگ آمیزی دینامیکی می نامند اگر در همسایه های هر رأس v?v(g) با درجه ی حداقل 2، حداقل 2 رنگ متفاوت ظاهر شوند. کوچکترین عدد صحیح k، به طوری که g دارای –kرنگ آمیزی دینامیکی باشد را عدد رنگی دینامیکی g می نامند و آنرا با نماد ?_2 (g) نمایش می دهند. مونت گمری حدس زده است که تمام گراف های منتظم ...
15 صفحه اولComputational Aspects of Graph Coloring and the Quillen–Suslin Theorem
We generalize both the Fibonacci and Lucas numbers to the context of graphcolorings, and prove some identities involving these numbers. As a corollary we obtain newproofs of some known identities involving Fibonacci numbers such asFr+s+t = Fr+1Fs+1Ft+1 + FrFsFt − Fr−1Fs−1Ft−1.
متن کاملAutomatic Service Composition Based on Graph Coloring
Web services as independent software components are published on the Internet by service providers and services are then called by users’ request. However, in many cases, no service alone can be found in the service repository that could satisfy the applicant satisfaction. Service composition provides new components by using an interactive model to accelerate the programs. Prior to service comp...

متن کاملAnts and Graph Coloring
Ants algorithm is an evolutionary search method for solving combinatorial optimization problems. In this note we propose a version of the algorithm for coloring a graph with a fixed number of colors. Based on approximate colorings obtained by single ants, edges of maximal evidence are added so that the new ants generation does only attempt to construct colorings with additional restrictions. Pr...
