Web System for Demonstrating the Syntactic Algorithms
for Solving Linear Equations in Nonnegative Integers
Dear
guest,
We consider a special class of homogenous NLDE systems
that are Associated with context-free grammars (ANLDE systems).
See an example
of such a system and its processing.
The attractive property of the demonstrated syntactic algorithm is
its polynomial complexity.
This makes the algorithm to be more efficient than "universal" solvers
of arbitrary NLDE systems; the syntactic solver can be used even
for large systems. For instance, the algorithm was tested on ANLDE
systems with dimensions up to 1000 equations, 1200 unknowns, and
coefficients in range [0,500]. Less than minute was spent by the
syntactic solver to find Hilbert basis for any of these systems.
For comparison, standard integer programming solvers might spend
several hours or even days to find only one solution, not the whole basis;
moreover they were failed to solve in reasonable
time some of these ANLDE systems.
More details about the ANLDE theory can be found
here.
Using Web-SynDic you can test our syntactic algorithm,
look at its efficiency, compare it with alternative algorithms.
Use the menu on the left of this page to access these features.
The basic Web-SynDic feature is processing
a single ANLDE system or
a set of ANLDE systems.
Limits of this processing are controlled with
algorithms configuration.
Your opinion about Web-SynDic can be given with
send notes feature.
Now you are working as a guest.
To access more function, you should
register and log in.
During this guest session you can change the algorithms configuration,
but the changes are lost whenever your session is over.
The lifetime of your session is not limited,
however the session is terminated after idle period of
15 min.
The explanation of the name "Web-SynDic" can be found
here.
