23    <p align="left">YALMIP 3 is a major revision compared to earlier versions.
24    The internal machinery of YALMIP has been rewritten, and the main result is
25    the possibility to work with nonlinear expressions. In addition, mixed
26    integer capabilities have been improved, and a number of new solvers have
27    been interfaced.</p>
