Aucune idée :yum:

Je suis tombé sur le package cvx (qui est un package de Matlab pour faire de l’optimisation convexe), et il a une licence qui pourrait t’intéresser : http://cvxr.com/cvx/doc/CVX.pdf (partie 1.4 : Licensing) et répondre en partie à ton problème.

With version 2.0, we have added the ability to connect CVX tocommercial solvers as well. This new functionality is released under a CVX Professional product tier which we intend to license to commercial users for a fee, and offer to academic users at no charge. The licensing structure is as follows:

  • All users are free to use the standard features of CVX at no charge. This includes the ability to construct and solve any of the models supported by the free solvers SeDuMi and SDPT3.
  • Commercial users who wish to solve CVX models using Gurobi or MOSEK will need to purchase a CVX Professional license. Please send an email to CVX Research for inquiries. for an availability schedule and pricing details.
  • Academic users may utilize the CVX Professional capability at no charge. To obtain an academic license, please visit the Academic licenses page on the CVX Research web site

Salut,
merci de ta réponse.
La particularité que je cherche (et que je ne trouve pas), c’est de permettre que les deux versions du programme soient identique. La seule difference est que l’une est “libre” (GPL), l’autre payante. Et le choix de la licence est donné à l’utilisateur.
merci !
