CAI is the biennial conference serving the community interested in the intersection of theoretical computer science, algebra, and related areas.

In 2019 it will feature invited presentations and a selective single-track program of contributed papers describing original and unpublished research.

*Important Dates*

Submission deadline: January 25, 2019 (DEADLINE EXTENDED)
Notification: March 15, 2019
Final version: April 5, 2019
Registration: May 20, 2019

*Submission Guidelines*

CAI 2019 invites authors to submit high-quality manuscripts (in PDF format) reporting original unpublished research in the topics covered by the conference.

Papers should be submitted electronically through EasyChair at the following link

https://easychair.org/conferences/?conf=cai2019

Submissions should be formatted according to the usual LNCS article style and should not exceed 12 pages (including all references). If additional space is needed, a clearly marked appendix can be added. The appendix will not be published, so the merit and results of the contribution should also be understandable without it.

Simultaneous submission to other conferences or workshops with published proceedings is not allowed. It is required that each accepted paper will be presented at the symposium by one of its authors.

*List of Topics*

Topics include, but are not limited to, the following areas of interest (ordered alphabetically). Papers covering other areas will be given due consideration by the program committee.
– abstract machines or systems
– acceptors and transducers for discrete structures
– algebraic and combinatorial methods in design theory
– algebraic aspects of cryptography
– algebraic characterization of logical theories
– algebraic coding theory
– algebraic semantics
– algebraic specifications and algorithms
– algorithms for construction and classification of designs
– complexity problems in design theory
– computational number theory
– decision problems

– hybrid automata
– implementation of symbolic algorithms
– molecular computing
– neural networks
– process algebra
– program construction and refinements
– quantitative automata models
– quantum computing
– symbolic mathematical computation
– term rewriting

*Publication*

*Proceedings*

The proceedings of CAI 2019 will be published in the Lecture Notes in Computer Science (LNCS) series by Springer.

*Special Issue*

Selected papers will be invited to a special issue of the Elsevier’s journal Information and Computation, devoted to CAI 2019.

*Venue*

CAI 2019 will take place in Niš (Serbia), one of the oldest cities in the Balkans and Europe, which since ancient times has been considered a gateway between the East and the West.
The conference is hosted at the University of Niš, and organized by the Faculty of Sciences and Mathematics of this university.

More information on the host can be found in the following websites:
