TANGO Trustable Algorithms for Nonlinear General Optimization
The University of Campinas and University of São Paulo joint project for optimization software development.


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.

TANGO is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation. Non-free versions of TANGO are available under terms different from those of the General Public License. Professors J. M. Martínez (martinez@ime.unicamp.br, martinezimecc@gmail.com) or E. G. Birgin (egbirgin@ime.usp.br, egbirgin@gmail.com) should be contacted for more information related to such a license, future developments and/or technical support.


TANGO project is being supported by the Brazilian agencies: FAPESP (Fundação de Amparo à Pesquisa do Estado de São Paulo), CAPES (Coordenação de Aperfeiçoamento de Pessoal de Nível Superior) and CNPq (Conselho Nacional de Pesquisa e Desenvolvimento).


The Department of Applied Mathematics at the Institute of Mathematics, Statistics and Scientic Computing of the University of Campinas, and the Department of Computer Science at the Institute of Mathematics and Statistics of the University of São Paulo also support the TANGO development group.
