We study the planning and acting phase for the problem of multi-agent path finding (MAPF) in this paper.

Contemporary SAT-based approaches to MAPF regard the SAT solver as an external tool whose task is to return an assignment of all decision variables of a Boolean model of input MAPF.

The integration of satisfiability testing by the SAT solver and the high-level construction of the encoding is however relatively loose in existing methods.

Each time a new conflict is discovered, the underlying encoding is extended with new variables and constraints to eliminate the conflict.

Search-based solvers were developed and tested for the sum-of-costs objective while the most prominent compilation-based solvers that are built around Boolean satisfiability (SAT) were designed for the makespan objective.

The key difference between the standard CBS and our SMT-based modification of CBS (SMT-CBS) is that the standard CBS branches the search to resolve the collision while in SMT-CBS we iteratively add a single disjunctive collision resolution constraint.
