Consider updating SLSQP to a modern and maintained implementation

7

# Description of feature Currently, the version of SLSQP provided is quite old, and suffers from several bugs that have been fixed elsewhere. See #301 for some discussion. Since SLSQP...

Provide decorators for skipping code if an optimizer is not available

3

# Description Dymos recently added a decorator in openmdao/dymos#570, which may be something we want to implement in pyOptSparse natively also. This could be useful for: - skipTest in pyOptSparse...

Store the optimal information in the history file

5

# Description of feature The optimal design is stored in the solution object, but not in the history file (remember that the final iteration may not be the optimal solution)....

# Description of feature The current setup is not very good---we use the same `Error` class for all exceptions, which means we cannot catch specific errors. Instead, we must resort...

Create a CLI tool to quickly plot optimization history

2

# Description of feature I'm thinking something like ``` plotOpt --vars "feasibility" "optimality" --vars "cruise_drag" "maneuver_drag" --vars "twist" --output opt.png ``` which will generate a 3x1 stacked plot of these...

Verify call counters and timings in Optimization object

2

## Description Check that the call counters are correct, even when using FD/CS etc. Also check that timings are set up correctly.

# Description ## Unit tests - [ ] test that the Solution object contains the right info - [x] `objectives` - [ ] `constraints` - [ ] `variables` - [...

Improve printing of optimization and solution objects

1

## Description The current `str()` implementation can be improved: - objective value should not be initialized to zero. Instead should be `None` and a placeholder text should be shown -...

## Description ### Steps to reproduce issue 1. Change `self.N` to 5000 in `test_large_sparse.py` 2. Run the IPOPT test ### Current behavior Optimization segfaults ### Expected behavior Optimization should complete...

## Description _Describe the bug here_ ### Steps to reproduce issue 1. Run an optimization with SNOPT, and store the history 2. Call `getValues` without specifying `values`, and with `major=False`...
