getReasons

@Deprecated
public Map<String,org.apache.commons.math3.stat.Frequency> getReasons()

Deprecated.

For each job id, it returns frequency distribution of failed constraints (simple name of constraint) in an unmodifiable map.

Returns:

getFailedConstraintNamesFrequencyMapping

public Map<String,org.apache.commons.math3.stat.Frequency> getFailedConstraintNamesFrequencyMapping()

For each job id, it returns frequency distribution of failed constraints (simple name of constraint) in an unmodifiable map.

Returns:

getCodesToReason

public Map<Integer,String> getCodesToReason()

Returns an unmodifiable map of codes and reason pairs.

Returns:

getFailedConstraintNamesToCode

public Map<String,Integer> getFailedConstraintNamesToCode()

Returns an unmodifiable map of constraint names (simple name of constraint) and reason code pairs.

Returns:

getCode

public int getCode(String failedConstraintName)

getHumanReadableReason

public String getHumanReadableReason(int code)

getHumanReadableReason

getMostLikelyReasonCode

public int getMostLikelyReasonCode(String jobId)

Returns the most likely reason code i.e. the reason (failed constraint) being observed most often.

1 --> "cannot serve required skill 2 --> "cannot be visited within time window" 3 --> "does not fit into any vehicle due to capacity" 4 --> "cannot be assigned due to max distance constraint of vehicle"

Parameters:
