متن کاملThe clique partitioning problem: Facets and patching facets
The clique partitioning problem (CPP) can be formulated as follows: Given is a complete graph G = (V, E), with edge weights wij ∈ R for all {i, j} ∈ E. A subset A ⊆ E is called a clique partition if there is a partition of V into nonempty, disjoint sets V1, . . . , Vk , such that each Vp (p = 1, . . . ,k) induces a clique (i.e., a complete subgraph), and A = ∪ p=1 {{i, j}|i, j ∈ Vp , i ≠ j}. Th...
متن کاملPublication Ethics: Many Facets, Collaboration Required
Sir, the recent publication on “Publication Ethics” is very interesting (1). The article by Fazly Bazzaz and Sadeghi demonstrated many interesting cases of misconducts. Indeed, the misconducts can be seen in many ways. As mentioned in the present publication, both author and editor can perform publication misconducts. Nevertheless, the problem has many more facets. Sometimes,...
متن کاملThe Circuit Polytope: Facets
Given an undirected graph G = (V;E) and a cost vector c 2 IRE , the weighted girth problem is to nd a circuit in G having minimum total cost. This problem is in general NP-hard since the traveling salesman problem can be reduced to it. A promising approach to hard combinatorial optimization problems is given by the so-called cutting plane methods. These involve linear programming techniques bas...
متن کاملOf Grain Boundary Facets
Abatraet-constraints on diffusive creep cavity growth along grain boundary facets are studied for the limiting case when all facets oriented approximately normal to an applied tensik load am uniformly cavitated. This situation represents the opposite limiting case to when cavitated facets are we&sepamted and do not intemct with each other. The analysis is done for a 3-D periodic polycrystallii ...
