Class GroebnerBaseSeqPairDistributed<C extends RingElem<C>>

java.lang.Object

edu.jas.gb.GroebnerBaseAbstract<C>

edu.jas.gb.GroebnerBaseSeqPairDistributed<C>

Type Parameters:

C - coefficient type

All Implemented Interfaces:

GroebnerBase<C>, Serializable

@Deprecated
public class GroebnerBaseSeqPairDistributed<C extends RingElem<C>>
extends GroebnerBaseAbstract<C>

Deprecated.

no direct alternative

Groebner Base distributed algorithm. Implements a distributed memory parallel version of Groebner bases. Using pairlist class, distributed tasks do reduction. Makes some effort to produce the same sequence of critical pairs as in the sequential version. However already reduced pairs are not rereduced if new polynomials appear.
