Test Set for IVP Solvers
release 2.2
|
Revision History
Release 2.2, August 2003:
- Two more solvers (MEBDFI and GAMD) are supported.
- Five well known stiff ODEs have been added:
van der Pol, Robertson, Oregonator, E5 and Beam.
- It is again possible to submit new test problems.
- New work precision diagrams reporting CPU-times against the mescd (mixed
error significant correct digits) have been generated for each problem
(mescd is what actually the solvers supported by the Test Set try to control).
- The reference solution has been recomputed for some problems.
- All the tests have been run on an Alpha server DS20E, 667 MHz,
and the related section, in the problems descriptions,
has been updated.
- ODE, DAE and IDE problems have been gathered into three different lists and
link to separated pages reporting a short description, work precision diagrams and
plots of the solutions.
- A short description of each solver together with its
related references, has been added in the descriptive part of the Test Set.
- Some minor changes have been made in the report.
September 2001:
- The Test Set moved from CWI to the University of Bari.
Release 2.1, September 1999:
- The formulation of the Chemical Akzo Nobel problem has been
improved. The problem is now an index 1 DAE instead of an ODE.
- The DAE case with full
Jacobian and banded mass matrix is now supported in the DASSL
driver.
- The plot of the solution components of the Ring Modulator
problem is now correct.
- A new problem, the Water Tube System, has been added.
- Web server statistics have been added.
- It is no longer possible to submit new test problems.
- Some minor editorial changes have been made in problem descriptions.

Release 2.0, December 1998:
- The drivers have been changed considerably.
Now there is one generic driver per solver, which can handle all problems for
which the solver is applicable.
- A new problem, the Slider Crank, has been added.
- Two more solvers (RADAU and MEBDFDAE) are supported.
- The descriptions of the origin of the problems
have been made more readable.
- Quite some bugs have been corrected.
