A note on a two-agent scheduling problem related to the total weighted late work

We revisit a two-agent scheduling problem in which a set of jobs belonging to two agents A and B (without common jobs) will be processed on a single machine for minimizing the total weighted late work of agent A subject to the maximum cost of …

Minimum rank and zero forcing number for butterfly networks

Zero forcing is a graph propagation process introduced in quantum physics and theoretical computer science, and closely related to the minimum rank problem. The minimum rank of a graph is the smallest possible rank over all matrices described by a …

An time algorithm to solve the minimum cost tension problem

This paper presents an $$O(n(m+n\log n)\log n)$$ O ( n ( m + n log n ) log n ) time algorithm to solve the minimum cost tension problem, where n and m denote the number of nodes and number of arcs, respectively. The algorithm is inspired by Orlin …

Restricted power domination and zero forcing problems

Power domination in graphs arises from the problem of monitoring an electric power system by placing as few measurement devices in the system as possible. A power dominating set of a graph is a set of vertices that observes every vertex in the …

A possible optimal design of one-way Hamming network H(n, 3) based on the minimum transmission latency

One-way Hamming network H(n, 3), namely directed Hamming network, is the cartesian product of n complete graphs $$K_{3}$$ K 3 and has been widely used in hypercube parallel computer for its high communication rate and availability. As one of the …
