Complexity of clique coloring and related problems
A k-clique-coloring of a graph G is an assignment of k colors to the vertices of G such that every maximal (i.e., not extendable) clique of G contains two vertices with different colors. We show that deciding whether a graph has a k-clique-coloring is Σ 2 -complete for every k ≥ 2. The complexity of two related problems are also considered. A graph is k-clique-choosable, if for every k-list-ass...
متن کاملSemidefinite programming relaxations for graph coloring and maximal clique problems
The semidefinite programming formulation of the Lovász theta number does not only give one of the best polynomial simultaneous bounds on the chromatic number χ(G) or the clique number ω(G) of a graph, but also leads to heuristics for graph coloring and extracting large cliques. This semidefinite programming formulation can be tightened toward either χ(G) or ω(G) by adding several types of cutti...
متن کاملOn the Complexity of Rainbow Coloring Problems
An edge-colored graph G is said to be rainbow connected if between each pair of vertices there exists a path which uses each color at most once. The rainbow connection number, denoted by rc(G), is the minimum number of colors needed to make G rainbow connected. Along with its variants, which consider vertex colorings and/or so-called strong colorings, the rainbow connection number has been stud...
متن کاملthe effect of task complexity on lexical complexity and grammatical accuracy of efl learners’ argumentative writing
بر اساس فرضیه شناخت رابینسون (2001 و 2003 و 2005) و مدل ظرفیت توجه محدود اسکهان (1998)، این تحقیق تاثیر پیچیدگی تکلیف را بر پیچیدگی واژگان و صحت گرامری نوشتار مباحثه ای 60 نفر از دانشجویان زبان انگلیسی بررسی کرد. میزان پیچیدگی تکلیف از طریق فاکتورهای پراکندگی-منابع تعیین شد. همه ی شرکت کنندگان به صورت نیمه تصادفی به یکی از سه گروه: (1) گروه موضوع، (2) گروه موضوع + اندیشه و (3) گروه موضوع + اندی...
