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).
-
MAXCYCLES=number
-
specifies the maximum number of cycles to return. The default is the positive number that has the largest absolute value representable
in your operating environment. This option works only when you also specify MODE=ALL_CYCLES.
-
MAXLENGTH=number
-
specifies the maximum number of links to allow in a cycle. Any cycle whose length is greater than number is removed from the results. The default is the positive number that has the largest absolute value that can be represented
in your operating environment. By default, nothing is removed from the results. This option works only when you also specify
MODE=ALL_CYCLES.
-
MAXLINKWEIGHT=number
-
specifies the maximum sum of link weights to allow in a cycle. Any cycle whose sum of link weights is greater than number is removed from the results. The default is the positive number that has the largest absolute value that can be represented
in your operating environment. By default, nothing is filtered. This option works only when you also specify MODE=ALL_CYCLES.
-
MAXNODEWEIGHT=number
-
specifies the maximum sum of node weights to allow in a cycle. Any cycle whose sum of node weights is greater than number is removed from the results. The default is the positive number that has the largest absolute value that can be represented
in your operating environment. By default, nothing is filtered. This option works only when you also specify MODE=ALL_CYCLES.
-
MAXTIME=number
-
specifies the maximum amount of time to spend finding cycles. The type of time (either CPU time or real time) is determined
by the value of the TIMETYPE=
option. The value of number can be any positive number; the default value is the positive number that has the largest absolute value that can be represented
in your operating environment. This option works only when you also specify MODE=ALL_CYCLES.
-
MINLENGTH=number
-
specifies the minimum number of links to allow in a cycle. Any cycle that has fewer links than number is removed from the results. By default MINLENGTH=1 and nothing is filtered. This option works only when you also specify
MODE=ALL_CYCLES.
-
MINLINKWEIGHT=number
-
specifies the minimum sum of link weights to allow in a cycle. Any cycle whose sum of link weights is less than number is removed from the results. The default is the negative number that has the largest absolute value that can be represented
in your operating environment. By default, nothing is filtered. This option works only when you also specify MODE=ALL_CYCLES.
-
MINNODEWEIGHT=number
-
specifies the minimum sum of node weights to allow in a cycle. Any cycle whose sum of node weights is less than number is removed from the results. The default is the negative number that has the largest absolute value that can be represented
in your operating environment. By default, nothing is filtered. This option works only when you also specify MODE=ALL_CYCLES.
-
MODE=option
-
specifies the mode for processing cycles.

Description
|
|
ALL_CYCLES
|
Returns all (unique, elementary) cycles found.
|
|
FIRST_CYCLE
|
Returns the first cycle found.
|
By default, MODE=FIRST_CYCLE.
-
OUT=SAS-data-set
-
specifies the output data set to contain the cycles found.
