The objective is a function of discrete variables only: jumpDist 1.
As a result, we set the MIP cutoff to 0.9995
Type of presolve applied: MIP presolve.
LP relaxation solved: objective = 144
Global search incomplete - no integer solution has been found
This may be a bug in the link instead of Xpress per se. Workaround: run again with default options will probably help.
