Sequence of start ranks used in a multi-stage expansion


  • Alias: rank_sequence

  • Arguments: INTEGERLIST

  • Default: 2


Each level entry of the start_rank_sequence applies to one expansion within a multi-stage expansion. Current multi-stage expansions that support start rank sequences include multilevel and multifidelity function train expansions.

If adaptive refinement is active, then this sequence specifies the starting point for each level within either an individual or integrated refinement approach.

A corresponding scalar specification is documented at, e.g., start_rank
