24 | Version 4-0-0 is a milestone relase of Singular. |
---|
25 | The new release series 4 aims for an entirely modularized system |
---|
26 | simplifying connectivity with other systems and paving the way |
---|
27 | for parallel computations. |
---|
28 | As one step in this direction, in Singular 4-0-0, |
---|
29 | the representation of coefficient rings has been separated from the representation |
---|
30 | of polynomials which allows for easy integration of new types of coefficient fields. |
---|
31 | |
---|
32 | @sc{Singular} 4-0-0's list of improvements and new |
---|
33 | functionality further extends that of |
---|
34 | the 3-1-6/7 pre-release series. |
---|
35 | One highlight is the implementation |
---|
36 | of Walther's algorithm for computing deRham cohomology. |
---|
