Uno v1.0.0

[cvanaret]

Uno v1.0.0 allows combinations of the following strategies:

• constraint relaxation strategies: l1 relaxation and l1 feasibility restoration.
• subproblems: QP, LP and primal-dual barrier.
• globalization strategies: l1 merit function and filter method (with standard filter or nonmonotone filter).
• globalization mechanisms: line search and trust-region method.

Some combinations are at the moment not fully supported, namely barrier + trust-region (disabled) and l1 merit function + feasibility restoration (Uno issues a warning). This will be improved in later versions of Uno.

The only existing interface is to AMPL (.nl files).

This discussion was created from the release Uno v1.0.0.

Is there an API to create UNO problems? or is it still through AMPL?

[cvanaret]

At the moment, there's only an interface to AMPL. I'll update the announcement ;)

We implemented an UNO interface to Casadi such that you could model your problems in Python or Matlab, but it is not 100% finished yet.
