  This paper describes an efficient method for solving the classical string
equations of motion in (2+1)-dimensional anti-de Sitter spacetime. Exact string
solutions are identified that are the analogs of piecewise linear strings in
flat space. They can be used to approximate any smooth string motion to
arbitrary accuracy. Cusps on the string move with the speed of light and their
collisions are described by a Picard-Lefschetz-type formula. Explicit examples
are shown with the string ending on two boundary quarks. The technique is
ideally suited for numerical simulations. A Mathematica notebook that has been
used to generate the relevant figures is also included.
