  These are notes from a multi-year learning seminar on the algebraic approach
to Constraint Satisfaction Problems (CSPs). The main topics covered are the
theory of algebraic structures with few subpowers, the theory of absorbing
subalgebras and its applications to studying CSP templates which can be solved
by local consistency methods, and the dichotomy theorem for conservative CSP
templates. Subsections and appendices cover supplementary material.
