Subject: [gecode-users] seg. fault
Date: Wed, 16 May 2007 16:50:05 +0000
Hi all,
I have two questions that I could'nt help myself though some time passed..
1) This piece returns me a segmentation fault.
with an initialized matrix M(r,c), I want to have boolean operations on
cells.
Cells = BoolVarArray(this, r*c, 0, 1);
Row = BoolVarArray(this, r, 0, 1);
1. for(i to r)
2. for(j to c)
3. current = M[i][j];
4. if(M[i][j] > 0)
5. bool_or(this, Row[i], Cells [current], Row [i]);
6. else
7. BoolVar negate = BoolVar(this, 0,1);
8. bool_not(this, Cells [current], negate);
9. bool_or(this, Row [i], negate, Row [i]);
simply I disjunt every cell in the rows into RowBoolArray.
But this gives me segmentation fault.
When I comment out 5,7,8,9 it terminates safely.
Is there a missing initialization in my BoolArrays or sth else may be??
2) I could not find how to use matrix under minimodel for the Slice
operator.
declaration with
MiniModel::Matrix<IntVarArray> sub_matrix = matrix.slice(0,r,c,r',c');
rel(this, sub_matrix.row(1), IRT_EQ, sub_matrix.row(2));
error: conversion from
`Gecode::MiniModel::Matrix<Gecode::IntVarArray>::Slice' to non-scalar type
`Gecode::MiniModel::Matrix<Gecode::IntVarArray>' requested
Isnt a slice is again a matrix wrappered for IntVarArray ?
Thank you in advance,
Regards
penche
