SR1Factory

public SR1Factory()

Public so callers can construct a fresh factory per build instead of mutating the shared SR1.FACTORY singleton (whose state leaks across calls and tests). Same fix pattern as ScalarFunction.ScalarFunctionFactory.

Method Details

minDenominator

public SR1.SR1Factory minDenominator(double minDenominator)

Set the minimum denominator magnitude allowed in the update, scaled by a normalization factor. When the condition is violated the update is skipped. Default 1e-8.

Parameters:

minDenominator - denominator-magnitude threshold

Returns:

this factory, for chaining

build

public SR1 build()

Build a configured SR1 instance.

Returns:

a fresh SR1 with the configured options
