The OPTNET Procedure

TRANSITIVE_CLOSURE Statement

  • TRANSITIVE_CLOSURE < options >;

  • TRANSCL < options >;

The TRANSITIVE_CLOSURE statement invokes an algorithm that calculates the transitive closure of an input graph.

Transitive closure is described in the section Transitive Closure.

You can specify the following options in the TRANSITIVE_CLOSURE statement:

LOGLEVEL=number

controls the amount of information that is displayed in the SAS log. Table 2.22 describes the valid values for this option.

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 transitive closure results.
