Minimization of ordered, symmetric half-products
نویسنده
چکیده
We introduce a class of pseudo-Boolean functions called ordered, symmetric half-products. The class includes a number of well known scheduling problems. We study sets of dominating solutions for minimization of the half-products, and we show their fully polynomial time approximation schemes that use a natural rounding scheme to obtain 2-solutions in O(n/2) time.

The symmetric monoidal closed category of cpo $M$-sets
In this paper, we show that the category of directed complete posets with bottom elements (cpos) endowed with an action of a monoid $M$ on them forms a monoidal category. It is also proved that this category is symmetric closed.
متن کاملOrdered Weighted Averaging Operators and their Generalizations with Applications in Decision Making
The definition of ordered weighted averaging (OWA) operators and their applications in decision making are reviewed. Also, some generalizations of OWA operators are studied and then, the notion of 2-symmetric OWA operators is introduced. These generalizations are illustrated by some examples.
متن کاملResponse of Two Temperatures on Wave Propagation in Micropolar Thermoelastic Materials with One Relaxation Time Bordered with Layers or Half Spaces of Inviscid Liquid
The present study is concerned with the propagation of Lamb waves in a homogeneous isotropic thermoelastic micropolar solid with two temperatures bordered with layers or half spaces of inviscid liquid subjected to stress free boundary conditions. The generalized theory of thermoelasticity developed by Lord and Shulman has been used to investigate the problem. The secular equations for symmetric...
متن کاملSum-of-Generalized Products Expressions Applications and Minimization
This paper defines the sum-of-generalized-products expression (SOGP), a generalization of a sum-of-products expression (SOP), which is suitable for FPGA implementation. 2k-valued logic is introduced to design circuits with k-input LUTs. Minimization methods for SOGPs are developed. Experimental results show that SOGPs require many fewer products than SOPs, especially for symmetric functions and...
متن کاملWitt rings of quadratically presentable fields
This paper introduces an approach to the axiomatic theory of quadratic forms based on {tmem{presentable}} partially ordered sets, that is partially ordered sets subject to additional conditions which amount to a strong form of local presentability. It turns out that the classical notion of the Witt ring of symmetric bilinear forms over a field makes sense in the context of {tmem{quadratically p...
