# Computing the Overall Score for an Edge Pattern Candidate

For each edge pattern candidate, once the Caliper tool has computed the raw score for each scoring method and applied the scoring function for that scoring method it computes an overall score for the edge pattern candidate.

The Caliper tool computes the overall score for an edge pattern candidate by taking the Nth root of the product of the mapped scores. For example, if you defined four scoring methods, the Caliper tool would multiply the four scores and take the 4th root of the result.

Note that if any single scoring function produces a value of 0, then the overall score for the edge pattern candidate will also be 0.

The following figure shows the overall process of computing the score for an edge pattern candidate.
