The Laboratory carries out weekly global Seminar, where both classic and recent accomplishments in the area of programming languages and tools are discussed. The seminar is open to everyone – join the mailing list for announcements.

Attending the seminar is mandatory for Lab faculty and post-graduates, and highly recommended for all students. In the autumn semester of 2020, the seminar takes place on Mondays at 17:30, online in Google Meet.

    СFPQ with all-path query semantics

    At the seminar, we will talk about a matrix algorithm for context-free path querying with all-path semantics, which requires returning all the paths found that match the query. The implementation of this algorithm uses SuiteSparse implementation of the GraphBLAS standard that defines standard building blocks for graph algorithms in the language of linear algebra. We will compare the resulting implementation with the tensor algorithm implementation for all-path semantics.
