关于有固定工件和序约束的单机最小化最大流程排序问题的注记(A short note on the approximability of the single machine scheduling problem to minimize makespan with fixed jobs and precedence constraints)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2008
The single machine scheduling problem to minimize makespan with fixed jobs and precedence constraints is considered. There are some fixed jobs which are already fixed in the schedule.

Inhomogeneous diophantine approximation with prime constraints

open access: yesProceedings - Mathematical Sciences, 2018
The present article is some continuation of previous researches of the authors and is devoted to the inhomogeneous version of the problem of Diophantine approximation on lines under primality constraints. The main attention is given to ``the more general problem of inhomogeneous Diophantine approximation with prime constraints on lines in \(\mathbb R^d\

Multitime multiobjective variational problems via η-approximation method [PDF]

open access: yesYugoslav Journal of Operations Research, 2022
The present article is devoted to multitime multiobjective variational problems via η-approximation method. In this method, an η-approximation approach is applied to the considered problem, and a new problem is constructed, called as η- approximated ...

Submodular Stochastic Probing on Matroids [PDF]

open access: yes, 2014
In a stochastic probing problem we are given a universe $E$, where each element $e \in E$ is active independently with probability $p_e$, and only a probe of e can tell us whether it is active or not. On this universe we execute a process that one by one

Approximately Stable Matchings With Budget Constraints

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2018
This paper examines two-sided matching with budget constraints where one side (a firm or hospital) can make monetary transfers (offer wages) to the other (a worker or doctor). In a standard model, while multiple doctors can be matched to a single hospital, a hospital has a maximum quota; thus, the number of doctors assigned to a ...

Global Cardinality Constraints Make Approximating Some Max-2-CSPs Harder [PDF]

open access: yes, 2019
Assuming the Unique Games Conjecture, we show that existing approximation algorithms for some Boolean Max-2-CSPs with cardinality constraints are optimal. In particular, we prove that Max-Cut with cardinality constraints is UG-hard to approximate within ~

Large-N Quenching in the Kazakov-Migdal Model [PDF]

open access: yes, 1993
To study the behavior of the Kazakov-Migdal at large N the quenched momentum prescription with constraints for treating the large N limit of gauge theories is used.

Design of Acoustic Equalization Filters for Headphones Based on Low-Rank Regularization

open access: yesIEEE Open Journal of Signal Processing
The use of equalization filters to achieve acoustic transparency can improve the sound quality of hearables and hearing aids. Finite impulse response (FIR) filters guarantee stability and offer a listening impression close to the open ear, but their ...

Family-Personalized Dietary Planning with Temporal Dynamics

open access: yes, 2017
Poor diet and nutrition in the United States has immense financial and health costs, and development of new tools for diet planning could help families better balance their financial and temporal constraints with the quality of their diet and meals. This
