ppl_pips problems
by Sven Verdoolaege 04 Feb '11

04 Feb '11

I'm in the process of writing a paper about my improvements to pip and I wanted to compare to the PPL implementation too. (At least, I'd like to compare the execution times. I probably won't be diving into source to find out which optimizations in isl have also been implemented in PPL.) However, ppl_pips seems to produce incorrect results on some test cases. I'm using version products_root-2871-gc02e988. (The git repo does not appear to have any tags for the releases.) For bart-big.pip, ppl_pips returns Parameter N = (3*L + 64) div 256 if N >= 1 and -3*L + 256*N >= 64 then {-K + M ; M - 2 ; M - 2 ; M - 2 ; M - 2 ; M - 2 ; M - 2 ; M - 2 ; M - 2 ; M - N} else _|_ Which essentially means that it only found a solutions for L = 64, while there should be a solution for every value of L in the context. For bouleti.pip, ppl_pips returns _|_ That is, it claims that there is no solution, while isl_pip and PipLib's exampleMP do find solutions. Here is one of them: [p0, p1, p2, p3, p4, p5] -> { [1, 11, 4, 1, 2, 1, 2, 2, 1] : p3 = 1 and p4 = 11 and p5 = 2 and p0 = 0 and p1 = 0 and p2 = 2 } The following iscc session demonstrates that this is indeed a solution Q := 24 17 1 0 0 0 -1 0 0 0 0 0 1 -1 1 0 0 0 0 1 0 0 0 0 0 0 -1 0 0 1 -1 1 0 0 0 0 1 0 0 0 0 -1 0 0 0 0 1 -1 1 0 0 0 0 1 0 0 0 0 0 0 0 -1 0 1 -1 1 0 0 0 0 1 0 0 0 0 0 1 0 0 0 -1 1 0 -1 0 0 0 1 -1 0 0 0 0 0 0 0 0 1 -1 0 1 0 0 0 1 0 -1 0 0 0 0 0 0 0 1 -1 0 0 1 0 0 1 0 0 1 0 0 0 0 0 0 -1 1 0 0 0 -1 -1 1 0 0 0 1 0 0 0 0 0 -1 0 0 0 0 0 -1 1 0 0 0 1 1 -1 0 0 0 -1 0 0 0 0 0 0 1 0 0 -1 0 0 0 2 0 0 -1 0 0 0 0 0 0 1 0 0 0 0 0 0 1 0 0 -1 0 0 0 0 0 -1 1 0 0 0 0 0 0 1 1 -1 -1 0 0 0 0 0 0 1 0 0 0 0 1 0 0 0 0 -1 0 0 0 0 0 -1 1 0 0 0 0 0 0 0 1 0 -1 0 0 0 0 0 -1 1 0 0 0 0 0 1 0 0 0 -1 0 0 0 0 0 -1 1 0 0 0 0 0 0 0 0 1 -1 0 0 0 0 0 -1 1 1 1 0 0 0 0 0 0 0 -2 2 0 -1 -1 0 0 1 0 0 0 2 0 0 0 0 0 -2 1 0 0 0 -1 0 1 0 -1 0 0 0 0 0 4 3 -6 0 0 0 0 0 0 1 0 0 0 0 4 3 0 0 0 -7 1 0 0 -1 0 0 1 1 1 1 0 0 0 -2 -4 -4 7 0 0 0 0 0 0 1 0 0 0 -2 -4 -4 0 0 0 10 -3 0 1 1 1 0 1 -1 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 ; {[1, 11, 4, 1, 2, 1, 2, 2, 1, 0, 0, 2, 1, 11, 2]} <= Q; True C := 1 8 1 0 -1 1 0 0 0 -1 ; {[0, 0, 2, 1, 11, 2]} <= C; True Also, I wonder if you have a parser for the output format of ppl_pips so that I could compare the results produced by ppl_pips with those produced by isl_pip. skimo

The baseline patch has been contributed by Marco Poletti. MIP_Problem now stores the input constraints as a sequence of Constraint*. In this sequence, we distinguish between owned constraints (whose resources are under control of the current MIP_Problem object) and inherited constraints (whose resources are shared with, and owned by, another MIP_Problem object). When starting a branch-and-bound computation looking for an integral feasible/optimal solution, we now inherit (rather than copy) the input constraints. The workaround greatly improves space/time efficiency on (mixed) integral problems, also providing a (simple and reasonable) partial solution to https://www.cs.unipr.it/mantis/view.php?id=62 The solution is still partial: a complete solution requires the implementation of a backtracking mechanism for incrementally added constraints.

This, in turn, affected Box::CC76_widening_assign(const T&, Iterator, Iterator): lower bound would not be computed correctly when the two iterators specify an empty list of stop points.

Module: ppl/ppl Branch: master Commit: 0643bb18e84c01bf0906b99dbef0005e55f664b4 URL: http://www.cs.unipr.it/git/gitweb.cgi?p=ppl/ppl.git;a=commit;h=0643bb18e84c… Author: Enea Zaffanella <zaffanella(a)cs.unipr.it> Date: Thu Feb 3 18:48:49 2011 +0100 Corrected a bug in cut generation. We were using %= instead of the helper function mod_assign(), which is meant to compute the *positive* modulus. For clarity, the helper function has been renamed as pos_mod_assign(). --- src/PIP_Tree.cc | 30 +++++++++++++++--------------- 1 files changed, 15 insertions(+), 15 deletions(-) diff --git a/src/PIP_Tree.cc b/src/PIP_Tree.cc index 1e439df..23ba881 100644 --- a/src/PIP_Tree.cc +++ b/src/PIP_Tree.cc @@ -35,9 +35,9 @@ namespace { // Calculate positive modulo of x % y inline void -mod_assign(Coefficient& z, - Coefficient_traits::const_reference x, - Coefficient_traits::const_reference y) { +pos_mod_assign(Coefficient& z, + Coefficient_traits::const_reference x, + Coefficient_traits::const_reference y) { z = x % y; if (z < 0) z += y; @@ -187,7 +187,7 @@ complement_assign(Row& x, --x_0; else { PPL_DIRTY_TEMP_COEFFICIENT(mod); - mod_assign(mod, x_0, den); + pos_mod_assign(mod, x_0, den); x_0 -= (mod == 0) ? den : mod; } if (x_0 == 0) @@ -1952,7 +1952,7 @@ PIP_Tree_Node::compatibility_check(Matrix& s) { cut = s_mi; for (Row::iterator j = cut.begin(), j_end = cut.end(); j != j_end; ++j) - mod_assign(*j, *j, den); + pos_mod_assign(*j, *j, den); cut[0] -= den; scaling.push_back(den); } @@ -2350,7 +2350,7 @@ PIP_Solution_Node::solve(const PIP_Problem& pip, Row row(tableau.t[i]); PPL_DIRTY_TEMP_COEFFICIENT(mod); Coefficient& row0 = row[0]; - mod_assign(mod, row0, tableau_den); + pos_mod_assign(mod, row0, tableau_den); row0 -= (mod == 0) ? tableau_den : mod; const bool compatible = compatibility_check(context, row); // Maybe update sign (and first_* indices). @@ -2807,7 +2807,7 @@ PIP_Solution_Node::solve(const PIP_Problem& pip, const Row& t_i = tableau.t[i]; for (Row::const_iterator j = t_i.begin(), j_end = t_i.end(); j != j_end; ++j) { - mod_assign(mod, *j, den); + pos_mod_assign(mod, *j, den); if (mod != 0) ++pcount; } @@ -2841,7 +2841,7 @@ PIP_Solution_Node::solve(const PIP_Problem& pip, const Row& t_i = tableau.t[i]; for (Row::const_iterator j = t_i.begin(), j_end = t_i.end(); j != j_end; ++j) { - mod_assign(mod, *j, den); + pos_mod_assign(mod, *j, den); if (mod != 0) { score += den; score -= mod; @@ -2856,7 +2856,7 @@ PIP_Solution_Node::solve(const PIP_Problem& pip, const Row& s_i = tableau.s[i]; for (Row::const_iterator j = s_i.begin(), j_end = s_i.end(); j != j_end; ++j) { - mod_assign(mod, *j, den); + pos_mod_assign(mod, *j, den); s_score += den; s_score -= mod; } @@ -2950,7 +2950,7 @@ PIP_Solution_Node::generate_cut(const dimension_type index, Row::const_iterator j = row_t.begin(); Row::const_iterator j_end = row_t.end(); if (j != j_end && j.index() == 0) { - mod_assign(mod, *j, den); + pos_mod_assign(mod, *j, den); ++j; if (mod != 0) { // Optimizing computation: expr += (den - mod); @@ -2964,7 +2964,7 @@ PIP_Solution_Node::generate_cut(const dimension_type index, Variables_Set::const_iterator p_j = parameters.begin(); dimension_type last_index = 1; for ( ; j != j_end; ++j) { - mod_assign(mod, *j, den); + pos_mod_assign(mod, *j, den); if (mod != 0) { // Optimizing computation: expr += (den - mod) * Variable(*p_j); coeff = den - mod; @@ -3033,7 +3033,7 @@ PIP_Solution_Node::generate_cut(const dimension_type index, Row::iterator itr1 = ctx1.end(); Row::iterator itr2 = ctx2.end(); if (j != j_end && j.index() == 0) { - mod_assign(mod, *j, den); + pos_mod_assign(mod, *j, den); if (mod != 0) { itr1 = ctx1.insert(0, den); *itr1 -= mod; @@ -3054,7 +3054,7 @@ PIP_Solution_Node::generate_cut(const dimension_type index, --(*itr2); } for ( ; j != j_end; ++j) { - mod_assign(mod, *j, den); + pos_mod_assign(mod, *j, den); if (mod != 0) { const dimension_type j_index = j.index(); itr1 = ctx1.insert(itr1, j_index, den); @@ -3099,14 +3099,14 @@ PIP_Solution_Node::generate_cut(const dimension_type index, for (Row::const_iterator j = row_s.begin(), j_end = row_s.end(); j != j_end; ++j) { itr = cut_s.insert(itr, j.index(), *j); - *itr %= den; + pos_mod_assign(*itr, *itr, den); } } { Row::iterator cut_t_itr = cut_t.end(); for (Row::const_iterator j = row_t.begin(), j_end = row_t.end(); j!=j_end; ++j) { - mod_assign(mod, *j, den); + pos_mod_assign(mod, *j, den); if (mod != 0) { cut_t_itr = cut_t.insert(cut_t_itr, j.index(), mod); *cut_t_itr -= den;
