Numerical Algorithms for Nonlinear Dynamics
&
Existing Program Implementations

JANET drops out a little from a direction which I tried to set, it is more likely a general purpose package for studying nonlinear dynamics. It was an attempt to collect almost everything required to compile a program which will do what ever you want. But there is also interactive GUI environment with EquationEditor, with which you can set your system equations in pseudocode and perform a standard set of actions, such as computing and visualizing the basins of attraction, visualization of dynamics, etc. There are opportunities to carry out bifurcation analysis, however, its today's status is non-comparable with monsters like CONTENT or AUTO.

The package includes libraries of subroutines to carry out the diversified studyings. There are, as I’ve already mentioned, opportunities to use automatic differentiation (nowadays it’s hardly surprising), there is a bunch of methods for solving systems of differential equations, there are procedures for numerical continuation of solutions, for computing invariant manifolds, basins of attraction, bifurcation analysis, etc. However, there is a lack of manuals, or tutorials – without training materials it is impossible to take advantage of all these riches. There is, certainly, API reference, in standard JAVADOC format, there are examples, there is a bit of contextual help, but this is not enough for a real-time work.

Current version (1.10) was not updated for two years now and , I'm afraid, the peak of activity of developers is far behind. It's a pity, the project was promising, though, arrogant a bit, but, evidently, remains unfinished, at least in that part which is accessible in the Internet
