    Subclasses of PlanSelection in org.apache.sysds.hops.codegen.opt
    Modifier and Type | Class and Description
    --- | ---
    `class` | `PlanSelectionFuseAll` This plan selection heuristic aims for maximal fusion, which potentially leads to overlapping fused operators and thus, redundant computation but with a minimal number of materialized intermediate results.
    `class` | `PlanSelectionFuseCostBased` This cost-based plan selection algorithm chooses fused operators based on the DAG structure and resulting overall costs.
    `class` | `PlanSelectionFuseCostBasedV2` This cost-based plan selection algorithm chooses fused operators based on the DAG structure and resulting overall costs.
    `class` | `PlanSelectionFuseNoRedundancy` This plan selection heuristic aims for fusion without any redundant computation, which, however, potentially leads to more materialized intermediates than the fuse all heuristic.
