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.
