Options:
Mode:
These options affect the ordering of inequalities to be added at each iteration of DDM.
-minindex
-lexmax
-random
-mincutoff
-maxcutoff
-minridges
-maxridges
Order:
If options -mincutoff -maxcutoff -minridges -maxridges are chosen then only -noprefixedorder is possible. In other cases both options are available; the default one is -prefixedorder.
-prefixedorder
-noprefixorder
Graphinc:
These affect the way of determining adjacent vectors.
-graphinc
-nographinc
Arith:
By default, arbitrary precision integer arithmetic is used. Option -int forces to use ordinary (4 bytes) integer precision arithmetic. Option -float forces to use double floating point (8 bytes) arithmetic.
-bigint
-int
-float
Adjacency:
Option -adjacency forces to find also all pairs of adjacent vectors in the skeleton.
-noadjacency
-adjacency
Plusplus:
If option -plusplus is chosen then only the pairs of adjacent vectors that will be necessary on the future iterations are constructed. If option -noplusplus is chosen then all ridges are constructed on each iteration.
-plusplus
-noplusplus
Zerotol:
The option affects only if option -float is used. This is used to change a zero tolerance for floating point computation. A real value is considered as zero if its absolute value is at most the tolerance. The default value for the zero tolerance is 1e-8.
