Uno v1.0.0
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).
