ACA 2020 will not Occur
Hello everyone. We regret to inform you that ACA'2020 will not occur. This is unfortunate as a number of really interesting sessions have been proposed, but health considerations are paramount, and at this point in time, we don't expect it will be possible to hold this conference, in Athens or elsewhere in 2020.
This announcement should come as no surprise. We expect other CA conferences, such as ISSAC, will suffer similar fates. We have decided, rather than cancel, to postpone the meeting until the situation settles down, either later in the year or more likely by one year, having it in Athens in 2021, dates to be decided later (We will pay special attention to how ISSAC is rescheduled as these two conferences were originally designed to be in sync this year). Ilias and Dimitris Simos have put a great deal of effort already in organizing this conference, and I appreciate their efforts and those of all the session organizers.

Nowadays, it is well-known that also long-standing open problems in Algebraic Geometry can benefit of algorithmic methods that are developed by Computer Algebra.
The first obvious reason is that algorithms allow the construction of examples, from which researchers can deduce possible solutions to the questions they deal with. In this context, the necessity to design new algorithms for specific topics of interest or to optimize the existing ones often arises. Indeed, several existing algorithms theoretically allow some explicit computations (e.g. Groebner Bases) but in practice they do not give the desired result in a reasonable time, or using a reasonable amount of memory.
The second less obvious reason is that projecting an algorithm can give a new insight in the problem one is trying to solve: on the one hand, the algorithmic approach to a problem gives the chance to prove a statement in a constructive way; on the other hand, the effort needed to obtain a new Computer Algebra tool to tackle an open problem often allows to better enter the mechanism of the problem itself, highlighting new features that could not be seen with an existential approach.
As a consequence of the two above points, investigations in Algebraic Geometry from a computational point of view can also provide applications in other fields (e.g. coding theory, cryptography, computer graphics, data clouds).
This session aims at gathering specialists from different areas (Algebraic Geometry, Computer Algebra, Applied Mathematics) and discuss interactions between them.
Talks should focus on
algebraic and combinatorial aspects of problems in Algebraic Geometry;
algorithms and constructive methods for Algebraic Geometry and applications;
implementation of algorithms and optimization, possibly with comparisons with existing ones.
