Remarks

PMRedLine first finds candidate patterns at coarse granularity. High-scoring coarse results are then refined at fine granularity. A coarse result is considered "high-scoring" if its score exceeds an internally-computed coarse accept threshold.

By default PMRedLine determines the coarse accept threshold automatically. In exceptional cases you may need to override the automatic computation. You can override the automatic computation by setting CoarseAcceptThresholdFractionEnabled to "true". The coarse accept threshold will then be computed by multiplying together the coarse accept threshold fraction, specified by this value, and the AcceptThreshold.
