ParserNG

Parser 1.0.8 has been released on maven-central!

Bug fixes and more Android compatibility issues resolved.

Parser 1.0.6 has been released on maven-central!

Bug fixes and Android compatibility issues resolved.

Parser 1.0.5 has been released on maven-central!

Features bug fixes and optimizations in the scanning/semantic analysis stages.

Parser 1.0.4 has been released on maven-central!

This version features various optimizations and turbo capability for the Function class.

Parser 1.0.3 has been released on maven-central! Maintaining the industry standard besting speeds of v1.0.x, it adds the functionality of rotational geometry. In v1.0.3, you can use the rotor function, rot to rotate raw points in 3D space and other functions such as curves, lines, surfaces(both plane and curved) and 3D equations of all sorts.

ParserNG 1.0.2 has been released on maven-central!

Version 1.0.2 retains the wild speeds of Version 1.0.1. Adds an extra widening technique of variable passing to the Turbo mode, In addition to the current method of array based passing. The widening technique can be sometimes faster than the array based methods, but their speed profiles and memory profiles are similar. Its weakness though is that it cannot use more than 63 variables per expression, whereas the array based approach allows in theory any number up to the max integer size.

ParserNG 1.0.1 has been released on maven-central!

This close update ensures that Turbo mode's memory profile stays close to that of the normal mode, which is, nigh zero.

ParserNG 1.0.0 has been released on maven-central!

The library has finally come of age with the introduction of its Turbo mode, which offers a massive speed boost over its normal mode. The nomal mode already beats famous libraries like exp4J, and rivals Janino, the widely acclaimed Gold Standard of Java math parser speed measurements, very closely

ParserNG 0.2.5 has been released on maven-central

  1. Functions like intg, root, t_root and quadratic have been fixed and are working well. .

  2. Frame based args passing is used to milk to milk the last drops of performance during iterations.

  3. Constant folding and strength reduction make the evaluation process feel much faster.

  4. The print function that can be used to view the contents of an EvalResult which the solveGeneric() method returns is also functional.

  5. If you need a rich, fully featured parser that can do 3 million to 10 million evaluations per second, ParserNG v0.2.5 is the one for you.

ParserNG 0.2.4 has been released on maven-central!

ParserNG 0.2.4 drives the limits of expression interpretation velocity even further than all previous versions, beating many lighterweight and fast Java math parsers(interpreted) in many benchmarks.

Check ParserNG-Wars for some shootouts between ParserNG and other parsers, both handrafted benchmarks and JMH based ones

ParserNG evaluates expressions at almost the speed at which the expressions would run if they were compiled statements in Java code. Typical values for moderate expression evaluation speeds are between 85ns(algebraic expressions e.g.((12+5)*3 - (45/9))^2 to 176ns(methods with trig. functions, e.g. (sin(3) + cos(4 - sin(2))) ^ (-2)).

Applications that need 5 million to 10 million points generated per second would benefit from ParserNG v0.2.4

ParserNG 0.2.3 has been released on maven central!

comes with couple microsecond (on decent hardware and) expression solving ability while maintaining its full feature stack. Graphing feels butter-smooth and iterations shouldn't feel so iterative.

At 5 microsecond, moderately complex expressions such as

String s6 = "5*sin(3+2)/(4*3-2)";

can be evaluated almost 200 thousand times per second.

The model of a Matrix has also been optimized to use a 1D array internally. This makes it faster due to memory locality of Matrix data.

Also, we support eigenvalues and eigenvectors as inbuilt methods, so enjoy!

ParserNG 0.2.2 has been released on maven-central!**

What's new?

  1. Breaking change!!! Package name change. ParserNG now has a proper root package name, com.github.gbenroscience
  2. Really cool!!! -> Speed upgrades of up to 10x to 40x in the base algebraic expression parser. This means more speedy and energy efficient iterative calculations and graphing!
  3. Very nice to have -> ParserNG now comes with a Java platform agnostic graphing capability. All the developer needs to do is to implement 2 interfaces:
com.github.gbenroscience.math.graph.DrawingContext
com.github.gbenroscience.math.graph.AbstractView

and pass the instance to

com.github.gbenroscience.math.graph.Grid

So you can use the same codebase to plot graphs on Android, JavaFX, Swing and other Java platforms. We have made the required implementations of DrawingContext(so called adapters) for the most popular Java platforms(Android, Swing and JavaFX) available in GRAPHING.md If you have more platforms in mind, we will be excited to have you contribute the code and make ParserNG even more versatile. Enjoy!
