*Call for Papers* */Discrete Applied Mathematics/*// *Special Issue**: **Combinatorial Optimization ISCO 2022* *NEW DEADLINE: FEBRUARY 15, 2023 * ================================================================ We invite submissions of novel research articles for a special issue of /Discrete Applied Mathematics/on *Combinatorial Optimization*. This special issue will be dedicated to the International Symposium on Combinatorial Optimization ISCO 2022 that was held online on May 18–20, 2022. However, the special issue is also open to papers that were not presented at the conference. Contributions arising from papers given at the symposium should be substantially extended and should cite the conference paper. High-quality research papers are solicited to address theoretical as well as practical issues ofCombinatorial Optimization. Topics of interest include, but are not limited to: ·Approximation algorithms ·Branch-and-bound algorithms ·Branch-and-cut-and price algorithms ·Computational biology ·Computational complexity ·Computational geometry ·Constraint Programming ·Cutting plane algorithms ·Exact and parameterized algorithms ·Graph and network algorithms ·Interior point methods ·Linear and nonlinear (mixed-)integer programming ·Local search algorithms ·Multiobjective optimization ·On-line algorithms ·Polyhedral combinatorics ·Randomized algorithms ·Scheduling algorithms All submissions will be thoroughly refereed according to the high standards of /Discrete Applied Mathematics/. *Guide for authors can be found at: * https://www.elsevier.com/journals/discrete-applied-mathematics/0166-218x/gui... <https://www.elsevier.com/journals/discrete-applied-mathematics/0166-218x/guide-for-authors> Full papers must be submitted through the Elsevier Editorial Manager (EM) system (https://www.editorialmanager.com/dam/default1.aspx).  When submitting your paper, be sure to specify that the paper is a contribution for the special issue of *ISCO 2022*, so that your paper is assigned to the Guest Editors. Please see the Author Instructions on the site if you have not yet submitted a paper through EM. Be sure to note that your work is intended for the special issue and to select the article type *ISCO 2022*. The *NEW *deadline for submission is *FEBRUARY 15, 2023*. Accepted papers will be published online individually, before print publication. Additional information about the special issue can be obtained from the Guest Editors. We look forward to receiving your contribution. *Guest Editors:* Ivana Ljubic, ivana.ljubic@essec.edu Francisco Barahona, barahon@us.ibm.com Santanu Dey, santanu.dey@isye.gatech.edu A.
