OOQP is an objectoriented C++ package, based on a primaldual
interiorpoint method, for solving convex quadratic programming
problems (QPs). It contains code that can be used "out of the box" to
solve a variety of structured QPs, including general sparse QPs, QPs
arising from support vector machines, Huber regression problems, and
QPs with bound constraints.
OOQP also can be used as a framework can be used to design efficient
solvers for new classes of structured QPs. Its design allows for easy
substitution of the linear algebra modules, allowing different
standard linear algebra packages to be tried.
