Detailed Description

Solves the optimization problem with the new SNOPT 7.6 version.

Solves the optimization problem with SNOPT version 7.5 and below.

If you have an older of version of SNOPT installed, use snopt_adapter.h.

Given an optimization Problem with variables, costs and constraints, this class wraps it and makes it conform with the interface defined by SNOPT http://web.stanford.edu/group/SOL/guides/sndoc7.pdf

This implements the Adapter pattern. This class should not add any functionality, but merely delegate it to the Adaptee (the Problem object).

If you have a newer version of SNOPT installed, use snopt_adapter_76.h.

Given an optimization Problem with variables, costs and constraints, this class wraps it and makes it conform with the interface defined by SNOPT http://web.stanford.edu/group/SOL/guides/sndoc7.pdf

This implements the Adapter pattern. This class should not add any functionality, but merely delegate it to the Adaptee (the Problem object).
