Hello Barton,
I have downloaded altsimp.lisp and tried to execute the code.
In a Maxima session I loaded the code with load("altsimp.lisp"). But with gcl
2.6.8 and CLISP 2.46 on my system I get fatal errors and the Maxima session is
killed.
I have the same problems when I compile with compile_file("altsimp.lisp") and
load the object-file.
With CLISP I get a "Program stack overflow" in rtest9.mac.
When I use a batch-mode I get the following error with GCL 2.6.8 in
rexamples.mac (at this point the testsuite seems to kill my Maxima session):
********************** Problem 79 ***************
Input:
(kill(all), example(nusum))
Result:
(%i1) nusum(n*n!,n,0,n)
Dependent equations eliminated: (1)
(%o1) (n + 1)! - 1
(%i2) nusum(n^4*4^n/binomial(2*n,n),n,0,n)
4 3 2 n
2 (n + 1) (63 n + 112 n + 18 n - 22 n + 3) 4 2
(%o2) ------------------------------------------------ - ----
693 binomial(2 n, n) 33 7
(%i3) unsum(%,n)
4 n
n 4
(%o3) ----------------
binomial(2 n, n)
(%i4) unsum(product(i^2,i,1,n),n)
error-catch
This differed from the expected result:
Done
Do you have an idea what I should do?

My infinity correct simplus is now in CVS Maxima. Look for it in
.../share/contrib/altsimp/altsimp.lisp.
We welcome comments, improvements, extensions (infinity correct
multiplication, exponentiation, ...) , and ....
