Libopt: an environment for testing solvers on
heterogeneous collections of problems (with X. Jonsson).
M1CG1: implements a CG algorithm for solving in sequence large
scale linear systems with similar positive definite matrices; the solver generates an l-BFGS preconditioning matrix that can be
used to accelarate finding the solution of the next linear system.
large-scale unconstrained optimization by a limited memory BFGS method
(with C. Lemaréchal).
Qpalm, Oqla (with Émilie
Joannopoulos): two solvers of convex quadratic optimization problems, with the following features:
written in Matlab (Qpalm) and C++ (Oqla),
augmented Lagrangian method, with minimization of the augmented Lagrangian by an active set method,
can deal with an infeasible problem, in which case a solution to the closest feasible problem is computed,
can deal with an unbounded problem, in which case an unboundedness direction is computed,
the speed of convergence prescribed by the user is ensured (provided rounding error does not prevail),
adaptation to an SQP solver of nonlinear optimizatin problems.
Sdolab (version 0.4): Matlab code that solves a semidefinite optimization problem in complex numbers (dense
Small pieces of software
pgr (Matlab): polyhedral gauge recovery problem solver
(minimization of a polyhedral gauge on an affine subspace, with uniqueness detection).
nmhp 1.1 (Matlab): linear complementarity
problem solver by the Newton-min algorithm with the Harker and Pang globalization technique.
