links	—	specifies the input data table that contains the graph link information.
nodes	—	specifies the input data table that contains the graph node information.

Parameters for Creating Output Tables
Parameter	Subparameter	Description
out	—	specifies the output data table to contain the solution to the linear assignment problem.
outGraphList	—	specifies the output data table to contain summary information about in-memory graphs.
outLinks	—	specifies the output data table to contain the graph link information along with any results from the algorithms that calculate metrics on links.

Parameter Descriptions

deterministic=TRUE | FALSE

when set to True, ensures that each invocation (with the same machine configuration and parameter settings) produces the same final result.

Default	TRUE

direction="DIRECTED" | "UNDIRECTED"

specifies whether to consider the input graph as directed or undirected.

Default	UNDIRECTED

DIRECTED

considers the input graph to be directed. In a directed graph, each link (i,j) has a direction that defines how something (such as information) can flow over that link. In link (i,j), the flow is from node i to node j. Node i is called the source (tail) node, and node j is called the sink (head) node.

UNDIRECTED

considers the input graph to be undirected. In an undirected graph, each link {i,j} has no direction, and the flow can be in either direction. That is, {i,j} = {j,i}.

Alias	displayOut

selfLinks=True | False

when set to True, includes self-links when an input graph is read.

Default	True

standardizedLabels=True | False

when set to True, specifies that the input graph data are in a standardized format.

Default	False

standardizedLabelsOut=True | False

when set to True, requests that the output graph data include standardized format.

Default	False

timeType="CPU" | "REAL"

specifies whether to use CPU time or real time for the maximum time limit.

Default	REAL

CPU

specifies units of CPU time. The time restriction is applied per processing machine (not across all machines).

REAL

Result Descriptions

ProblemSummary

contains a basic summary of the graph input. The result is a table. You can access the value from results.ProblemSummary.

SolutionSummary

contains a basic solution summary for the algorithm. The result is a table. You can access the value from results.SolutionSummary.

objective

indicates the total weight of the minimum linear assignment. The result is a double. You can access the value from results.objective.

solutionStatus

indicates the solution status of the selected problem type (algorithm class). The result is a string. You can access the value from results.solutionStatus.

linearAssignment Action

Calculates the minimum-cost linear assignment (minimum link-weighted matching) of a bipartite graph.
