21 * @file ats/test_ats_mlp.c
22 * @brief test for the MLP solver
23 * @author Christian Grothoff
24 * @author Matthias Wachs
28 * @file ats/test_ats_api_scheduling_add_address.c
29 * @brief test for ats simplistic solver preference aging:
30 * Add 2 addresses and set high preference for one. Expect higher bw for this
31 * address, wait. Preferences should age and so bw assigned should decrease.
