Now I implemented cuts to strengthen the LP relaxation. However, I obtain the following problem when fathoming a node.<br><br>LP: Forcibly fathoming node in branch().<br>LP: Deleting 648 columns from the matrix.<br><br>Program received signal SIGSEGV, Segmentation fault.<br>0x00007ffff791ffd8 in OsiClpSolverInterface::OsiClpSolverInterface(OsiClpSolverInterface const&) () from /home/andi/Bcp-1.3.4/build/lib/libOsiClp.so.1<br><br>I first thought that my algorithmic cuts are including variables that have been deleted. However, if I customize the function "select_vars_to_delete" of BCP_lp_user to delete nothing the error still occurs.<br><br>Thanks a lot for your help.<br><br>With kind regards,<br><br>Andrea<br><br><br></body></html>
