# Built-in decision procedures and programmable tactics

Some tactics are largely automated and are able to solve complex goals. This chapter presents both some decision procedures that can be used to solve some specific categories of goals, and some programmable tactics, that the user can instrument to handle some complex goals in new domains.

- Omega: a solver for quantifier-free problems in Presburger Arithmetic
- Micromega: tactics for solving arithmetic goals over ordered rings
- The ring and field tactic families
- Nsatz: tactics for proving equalities in integral domains
- Generalized rewriting
