java.lang.Object
- edu.jas.gb.GroebnerBaseAbstract<C>
- - edu.jas.gb.GBSigBased<C>

All Implemented Interfaces:

edu.jas.gb.GroebnerBase<C>, java.io.Serializable
```
public class GBSigBased<C extends edu.jas.structure.GcdRingElem<C>>
extends edu.jas.gb.GroebnerBaseAbstract<C>
```
Groebner bases via signatur based GBs using jython script. TODO: Computing via the ScriptEngine is way slower than the direct execution in the jython interpreter. Check if a different engine is in the path or if it must be configured in some special way.
