ABS-Type Methods for Solving $m$ Linear Equations in $frac{m}{k}$ Steps for $k=1,2,cdots,m$
The ABS methods, introduced by Abaffy, Broyden and Spedicato, aredirect iteration methods for solving a linear system where the$i$-th iteration satisfies the first $i$ equations, therefore a system of $m$ equations is solved in at most $m$ steps. In thispaper, we introduce a class of ABS-type methods for solving a full rowrank linear equations, w...
متن کاملK-regular Antichains on [m] with K ≤ M-2
Let 2 be ordered by set inclusion and let B ⊆ 2 be an antichain of size n := |B|. An antichain B is k-regular for some non-negative integer k, if for each i ∈ [m] there are exactly k sets B1, B2, . . . , Bk ∈ B containing i. In this case we say that B is a (k, m, n)-antichain. Let 2 ≤ k ≤ m − 2 be positive integers. In this paper we show that a (k, m, n)-antichain exists if and only if k + 1 ≤ ...
متن کاملAn application of the Lovász-Schrijver M(K, K) operator to the stable set problem
Although the lift-and-project operators of Lovász and Schrijver have been the subject of intense study, their M(K , K ) operator has received little attention. We consider an application of this operator to the stable set problem. We begin with an initial linear programming (LP) relaxation consisting of clique and non-negativity inequalities, and then apply the operator to obtain a stronger ext...
متن کاملM M m K Queue With Additional Servers and Discouragement (RESEARCH NOTE)
Waiting in long queue is undesirable due to which in some practical situations customers become impatient and leave the system. In such cases providing additional servers can reduce long queue. This investigation deals with multi-server queueing system with additional servers and discouragement. The customers arrive in poisson fashion and are served exponentially by a pool of permanent and addi...
متن کاملEmergency Location Problems with an M/G/k Queueing System
Since late 1960's, the emergency location problems, fire stations and medical emergency services have attracted the attention of researchers. Mathematical models, both deterministic and probabilistic, have been proposed and applied to find suitable locations for such facilities in many urban and rural areas. Here, we review some models proposed for finding the location of such facilities, wit...
