[Help-glpk] GLPSOL solver running problem

[Le Van Duc]

Dear all,

I have implemented a mixed linear integer programming model using GNU MathProg language and run program using GLPSOL solver. While the program is running, the result has been shown as: 

...$ glpsol --model controlCoverageWithConnectivity2.mod --data dataInput.dat
GLPSOL: GLPK LP/MIP Solver, v4.45
Parameter(s) specified in the command line:
 --model controlCoverageWithConnectivity2.mod --data dataInput.dat

I do not know why the process is suddenly killed as above and the program is stopped. Please let me know what is problem and how to solve this.

Thank you so much!
