The Steiner tree problem (STP) in graphs is one of the most studied problems in
combinatorial optimization. Since its inception in 1970, numerous articles published in the …

The urgent desire to relieve the pressure of dependence on petroleum in energy industry
and the growing demand for protection of our environment stimulate the researches and …

A wide range of problems can be modeled as Mixed Integer Linear Programming (MIP)
problems using standard formulation techniques. However, in some cases the resulting MIP …

Precision agriculture is the collection of hardware and software technologies that allow a
farmer to make informed, differentiated decisions regarding agricultural operations such as …

Beginning in the 1960s, techniques from operations research began to be used to generate
political districting plans. A classical example is the integer programming model of Hess et …

We review and analyze the farming (upstream agribusiness supply chain) research literature
since 1965 to identify farming research opportunities for operations management (OM) …

When constructing political districting plans, prominent criteria include population balance,
contiguity, and compactness. The compactness of a districting plan, which is often judged by …

Mathematical modelling of market design issues in liberalized electricity markets often leads
to mixed-integer nonlinear multilevel optimization problems for which no general-purpose …

We consider the problem of information collection from a polygonal environment using a
multi-robot system, subject to continuous connectivity constraints. In particular, the robots …

This paper describes operational research (OR) contributions in forestry over the past 50
years, based on scientific pathways along which the authors have traveled. We draw on our …
