Method Detail

advanceParameter

public AdvanceType advanceParameter(double runResult)

shouldRevert

public boolean shouldRevert(double runResult)

Description copied from interface: AdvancementChooser

If the sweeper should revert to the parameters used before the last ones. For instance, if we executed 2 runs, first at (0, 0) and second at (1, 0) and the value of those runs were 100 and 50 respectively, it would most likely tell it to revert and go back to the (0, 0) parameters (because the value was "better").

Specified by:

shouldRevert in interface AdvancementChooser

Parameters:

runResult - the result of the previous run

Returns:

if the sweeper should revert or not

                                     AdvanceType lastType,
