无法使用WORHP运行SCIP

问题描述

我想尝试SCIP和WORHP来解决非线性优化问题。我无法运行abel.osil实例进行测试。

我的测试是在装有Ubuntu 18.04.5 LTS的Linux机器上进行的。 scip已配置

cmake .. -DCMAKE_INSTALL_PREFIX=$PWD -DPAPILO=OFF -DGMP=OFF -DZIMPL=OFF -DGCG=OFF -DWORHP=ON -DWORHP_DIR=/home/kimk/software/worhp

和gcc 6.5.0。

以下是在scip上运行worhp时的屏幕输出。

presolving (2 rounds: 2 fast,1 medium,1 exhaustive):

 0 implications,0 cliques
presolved problem has 29 variables (0 bin,29 cont) and 15 constraints
     14 constraints of type <linear>
      1 constraints of type <quadratic>
Presolving Time: 0.00
Quadratic constraint handler does not have LAPACK for eigenvalue computation. Will assume that matrices (with size > 2x2) are indefinite.
