Class Overview

Definition of a master optimizer, whose role is to manage and orchestrate the execution of individual optimizers.

Note about optimizer groups: currently, the way optimizers are run is as follows:

  • group 0: executed once, at first
  • group 1..N:
    • group 1 executed repeatedly until no more optimizations can be performed
    • group 2 is executed once; if optimizations were made, we go back to group 1; else, we move to group 3
    • group 3 is executed once; if optimizations were made, we go back to group 1; else, we move to group 4
    • etc.
  • group -1: executed once, at last
  • group -2: executed on-demand only (passive container)
