Opengen v0.6.0

Got an A+ on codefactory!

Added

• Support for half-spaces in problem constraints
• Added checks for segments in CartesianProduct

Changed

• Dropping first argument in Cartesian (dimension) as it is unnecessary
• Documented class CartesianProduct
• Dropped dimension from constructor of CartesianProduct (breaking change)

Fixed

• Issue #185: ROS config parameters are ignored

OpEn v0.7.0

Merge pull request #177 from alphaville/dev/v0.5.0

Release of new versions (opengen v0.5.0, open v0.7.0)

Opengen v0.5.0

OpEn can now generate ROS packages. Install opengen version 0.5.0 (available on pypi). The value of the cost function at the solution is returned by the solver.

Opengen v0.4.1

New version of opengen. Main changes:

• Project-specific icasadi dependency
• Project-specific tcp_iface TCP interface
• Fixed lbfgs typo

v0.6.2

v0.6.2

0.6.1

Fixed

• Fixed issue #121
• Unique C/C++ function names in icasadi (casadi_memory.h and interface.c)

ALM + PM

This is a major new release with code generation for problems with constraints that can be treated either with the augmented Lagrangian method or the penalty method; both types can be supported at the same time in Rust and Python. Updated documentation with lots of examples.

Note: We had previously announced the pre-release 0.6.1-alpha.2, that is, we skipped 0.6.0 by mistake, but at least that was in an unofficial alpha release. This is now an official release.

Rust version: 0.6.0
Opengen version (Python): 0.2.0

Fixed

• TCP server: Malformed error JSON is now fixed
• Algorithm now returns u_bar, which is feasible (not u)

Added

• Implementation of joint ALM/PM algorithm
• New AKKT-compliant termination criterion
• Tolerance relaxation in penalty method
• Finite sets supported in Rust
• Rust/Python: setting CBFGS parameters
• Second-order cones supported in Rust
• New support for C-to-Rust interface via bindgen
• Generation of example C code for C-to-Rust interface

Removed

• Support for Python <3.6 (deprecated)
• Homotopy module in Rust is annotated as deprecated

v0.6.1-alpha.2 (ALM/PM support)

New pre-release with code generation for problems with constraints that can be treated either with the augmented Lagrangian method or the penalty method; both types can be supported at the same time.

• Tolerance relaxation in penalty method
• Finite sets supported in Rust
• Rust/Python: setting CBFGS parameters
• Second-order cones supported in Rust

Removed

• Module continuation is going to become obsolete

v0.5.0

Fixed

• Fixed with_max_duration in PANOC not following the builder pattern
• Fixed misplaced .unwrap() in the HomotopyOptimizer
• Fixed so the Python builder uses the current directory as default

Added

• Generation of C/C++ bindings added in the Python interface and included in the test suite
• Support in Rust for Cartesian product of constraints

Removed

• Deprecated: enable_tcp_interface and enable_c_bindings_generation
