Class DurationFunctionThresholdCrossingIndicated

java.lang.Object

agi.foundation.numericalmethods.advanced.DurationFunctionFinding

agi.foundation.numericalmethods.advanced.DurationFunctionThresholdCrossingIndicated

public class DurationFunctionThresholdCrossingIndicated
extends DurationFunctionFinding

A finding by DurationFunctionExplorer that a threshold crossing is indicated somewhere between two durations, because the function values are on opposite sides of the threshold at the two durations. The precise duration at which the function crosses the threshold may not yet be known.

Initializes a new instance.

Parameters:

explorer - The instance that identified this threshold crossing.

function - The function that crossed the threshold.

threshold - The threshold that was crossed.

extremum - The extremum that led to the discovery of this crossing, or null if and extremum was not involved in the discovery of this crossing.

leftDuration - The duration to the left of the threshold.

leftValue - The function value to the left of the threshold.

rightDuration - The duration to the right of the threshold.

rightValue - The function value to the right of the threshold.
