The 14th International Conference and Workshop on Algorithms and Computation (WALCOM) is intended to provide an international forum for researchers working in the areas of algorithms and computation. WALCOM 2020 will be held during March 31 - April 02, 2020 at National University of Singapore, Singapore. It is being organized in cooperation between Institute of Mathematical Sciences (NUS), School of Computing (NUS), The Special Interest Group for ALgorithms (SIGAL) of the Information Processing Society of Japan (IPSJ), and Technical Committees on Theoretical Foundations of Computing (COMP) of The Institute of Electronics, Information and Communication Engineers (IEICE).

SCOPE 

The range of topics within the scope of WALCOM includes but is not limited to:

• Approximation Algorithms
• Algorithmic Graph Theory and Combinatorics
• Combinatorial Algorithms
• Combinatorial Optimization
• Computational Biology
• Computational Complexity
• Computational Geometry
• Discrete Geometry
• Data Structures
• Experimental Algorithm Methodologies
• Graph Algorithms
• Graph Drawing
• Parallel and Distributed Algorithms
• Parameterized Algorithms
• Parameterized Complexity
• Network Optimization
• Online Algorithms
• Randomized Algorithms
• String Algorithms

AUTHOR INSTRUCTIONS

Authors are invited to submit papers (extended abstracts) describing original research of theoretical or practical significance to algorithms and computation. Papers should not exceed 12 pages in LNCS style. Papers significantly shorter than 12 pages are also welcome. If the authors feel that more details are essential to substantiate the main claim of the paper, they may include a clearly marked appendix that will be read at the discretion of the Program Committee. Only electronic submissions via Easychair will be allowed (https://easychair.org/conferences/?conf=walcom2020). Papers submitted for review should represent original, previously unpublished work and surveys of important results. At the time the paper is submitted to WALCOM 2020, and for the entire review period, the paper (or essentially the same paper) should not be under review by any other conference with published proceedings or by a scientific journal. At least one author of each accepted paper will be expected to attend the conference and present the paper.

AWARDS 

Two awards, namely, "The Best Paper" and "The Best Student Paper" will be awarded. A paper is eligible for the Best Student Paper if the paper is presented by an author, who is a full-time student.

PROCEEDINGS AND SPECIAL ISSUE

Accepted papers will be published in the conference proceedings. Following the tradition of the previous editions of WALCOM the proceedings will be included in the Springer-Verlag series, Lecture Notes in Computer Science. Authors of selected papers will be invited to submit extended versions of their papers to Journal special issues in Theoretical Computer Science (TCS) and Journal of Graph Algorithms and Applications (JGAA).

IMPORTANT DATES

Paper submission deadline : September 15, 2019 (Anywhere on Earth)
Notification of Acceptance/Rejection: October 28, 2019
Camera-ready Submission and Author Registration: November 08, 2019
