create
Creates and configures an Industrial Strength COMPASS (ISC) solver for a given problem definition. ISC is a three-phase discrete-optimization-via-simulation method: a global Niching-GA exploration phase, a local COMPASS phase per niche, and a clean-up ranking-and-selection phase.
The single indifference-zone parameter deltaC controls the statistical guarantees and follows ISC's graceful-degradation convention: with deltaC > 0 the clean-up phase runs the Rinott indifference-zone selection and reports a ±δ_C interval with a correct-selection guarantee (and, with deltaL > 0, COMPASS confirms local optimality via Kim's 2005 test); with deltaC = 0 (the default, inherited from the problem's indifference-zone parameter) the solver still returns a feasible best but the indifference-zone guarantees are dropped.
Return
An instance of ISCSolver.
Parameters
The definition of the optimization problem, including constraints and objectives.
The model builder interface used to create models for evaluation.
The indifference-zone parameter δ_C. Defaults to the problem's indifference-zone parameter; 0.0 selects the degraded mode (no correct-selection guarantee), > 0 the full guarantees.
The COMPASS local-optimality indifference zone δ_L. Defaults to deltaC.
When true, skip the global Niching-GA phase and run a single COMPASS search from the starting point (the paper's unimodal shortcut). Defaults to false.
An optional replication budget added as a soft transition rule to the global phase.
Optional initial coordinates seeded as ISC's first solution (and first COMPASS seed). If left null, the solver auto-generates a random feasible starting point upon initialization.
The maximum number of orchestration macro-steps. Defaults to 1000.
The number of replications to use during each evaluation.
Specifies if the evaluator uses a solution cache. By default, this is MemorySolutionCache.
Specifies if the simulation oracle will use a SimulationRunCache. The default is null (no cache).
the run parameters to apply to the model during the building process
the random number stream number; 0 (the default) means the next available stream
the provider of random number streams shared by the ISC sub-solvers; defaults to a fresh RNStreamProvider
