infinite loop in simplify_indexed()
by PG CLARK 21 May '11

21 May '11

I've finally tracked down the source of my troubles in getting the little program I've been working on to run and I'm 99% convinced it's a bug in the library. Please take a look at this brief sample program I wrote that illustrates the problem. #include <iostream> #include <ginac/ginac.h> using namespace std; using namespace GiNaC; int main() { symbol i_sym("i"), j_sym("j"), k_sym("k"), l_sym("l"), m_sym("m"), n_sym("n"); idx i(i_sym, 2), j(j_sym, 2), k(k_sym, 2), l(l_sym, 2), m(m_sym, 2), n(n_sym, 2); symbol alpha_sym("\\alpha"), beta_sym("\\beta"), gamma_sym("\\gamma"); idx Va(alpha_sym, 3), Vb(beta_sym, 3), Vg(gamma_sym, 3); symbol U("U"), v("v"), h("h"); exvector IJKLMNVec; idx IJKLMNIA[] ={i, j, k, l, m, n}; IJKLMNVec.assign (IJKLMNIA,IJKLMNIA+6); ex myEx = (indexed(h, sy_symm(sy_none(0, 1), sy_none(2, 3),sy_none(4, 5)), IJKLMNVec)*indexed(U, i, Va)*indexed(v, j, Va)*indexed(U, k, Vb) *indexed(v, l, Vb)*indexed(U, m, Vg)*indexed(v, n, Vg)).simplify_indexed(); cout << myEx << endl; return 0; } You'll find it never terminates. simplify_indexed() has an infinite loop that was unanticipated caused by some rare forms of indexed expressions. This program will just run and run trapped in implify_indexed() and never print anything out. If a fix is not forthcoming any ideas for a work around? regards peter clark ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.
