    Description

      Goal: Improve APIs for optimization

      Motivation: There have been several disjoint mentions of improving the optimization APIs to make them more pluggable, extensible, etc. This JIRA is a place to discuss what API changes are necessary for the long term, and to provide links to other relevant JIRAs.

      Eventually, I hope this leads to a design doc outlining:

      • current issues
      • requirements such as supporting many types of objective functions, optimization algorithms, and parameters to those algorithms
      • ideal API
      • breakdown of smaller JIRAs needed to achieve that API
