Current ALGENCAN version is 3.1.0 (Last updated: November 7, 2016).

TANGO (Trustable Algorithms for Nonlinear General Optimization) is a set of Fortran routines for Optimization developed at the Department of Applied Mathematics of the State University of Campinas and at the Department of Computer Science of the University of São Paulo, under the coordination of Professor J. M. Martínez. Only well-established methods are included. The codes are easy to use and require minimum previous knowledge. On-line support is provided.
