Hi, I am trying to solve a network flow problem which has some integer constraints as well. Anyway, I've formulated the problem in CPLEX form, and glpsol then solves it, but it takes close to 10 minutes to do so. But when I use the API directly, calling lpx_read_cpxlp followed by calls to lpx_simplex and lpx_integer, I get the same optimal solution in less than a minute. Is there any reason why glpsol is so much slower (by almost an entire order of magnitude!) than direct calls to the API? I've tried looking through the archives but couldn't find any discussion on this. Any help on this would be appreciated. Many thanks in advance.
