Is there a symbolic computing library for Java, similar to Sympy?

Question

Java

I am looking for a symbolic computing library for Java with good documentation, similar to Sympy.
It is necessary to simplify the polynomial in symbolic form:
y = b_0 + x1*b1 + x2*b2 + x3*b3 + x1*x2*b12 + x1*x3*b13 + x2*x3*b23 + b123*x1*x2*x3
x1 = (f1-f1_0)/delta_f1
x2 = (f2-f2_0)/delta_f2
x3 = (f3-f3_0)/delta_f3 f1_0
-f3_0, delta_f1-f3, b_i = const Searched by keywords: java symbolic expression expand From what I found: Symja - Java Computer Algebra Library. https://bitbucket.org/axelclk/symja_android_librar...


Symja - Java computer algebra and symbolic math library. Differentiation, integration, equation solving, polynomial factorization and linear algebraic functions.
for some reason, the mirror on github is already called symja android library
https://github.com/axkr/symja_android_library
I connected the latest jar, added it to IntelliJ IDEA as a library, used examples taken from the bitbook. Not one of them started up, everything crashes with java.lang.ClassNotFoundException.

To create synergy between all sciences (eg math, physics, sociology, biology, astronomy, economics, etc.) by integrating them into a single architecture.
To provide the best on-line services (webstart) for scientific calculations and visualizations
I did not find anything useful for myself, it works with complex numbers, but this is far from what I need.

https://github.com/yuemingl/SymJava still found. It certainly wants strange (Java-OO)...
