Do you have an example Solve() expression?

[zhoukang]

Solve(x^(258)==1,x) Solve(y==((1-x)^(1/(2)))+((x+3)^(1/(2))),y) Solve(y==x+((1)/(x)),y) these are some expression from user

Profiling:

Solve(x^24==1,x)

[zhoukang]

Thanks @axelclk

[zhoukang]

any progress? @axelclk

[Axel Kramer]

I added the commit:

https://bitbucket.org/axelclk/symja_android_library/commits/6bdde7242baef3060ee15cda891eef0b081423f4

The Solve() function is now much faster, but no real improvement for the expression:

Solve(x^(258)==1,x) 

Note: the changes need more JUnit tests to see if all is workiing as expected.

ok,i will test in my project.thanks very much! @axelclk

Commit 7bffe17 improves performance for cyclotomic polynomials.

[Axel Kramer]

With the new JAS-2.6.5652 version commited as 72f92c1 the factorization of cyclotomic polynomials is also much faster.

Examples:

Factor(x^258-1)
Factor(x^259+1)
