The OPTNET Procedure

MINSPANTREE < options > ;

MST < options > ;

The MINSPANTREE statement invokes an algorithm that solves the minimum link-weighted spanning tree problem on an input graph.

The minimum spanning tree problem is described in the section Minimum Spanning Tree.

You can specify the following options in the MINSPANTREE statement:

LOGLEVEL=number | string

controls the amount of information that is displayed in the SAS log. Table 2.18 describes the valid values for this option.

Table 2.18: Values for LOGLEVEL= Option

number	string	Description
0	NONE	Turns off all algorithm-related messages in the SAS log
1	BASIC	Displays a basic summary of the algorithmic processing
2	MODERATE	Displays a summary of the algorithmic processing
3	AGGRESSIVE	Displays a detailed summary of the algorithmic processing

The default is the value that is specified in the LOGLEVEL= option in the PROC OPTNET statement (or BASIC if that option is not specified).

OUT=SAS-data-set

specifies the output data set to contain the solution to the minimum link-weighted spanning tree problem.
