A variant of locate/2,3 with interleaved squashing. The squash algorithm is applied once to the SquashVars initially, and then again after each splitting step (i.e. each time one of the LocateVars has been split nondeterministically during the search). A variable may occur in both LocateVars and SquashVars.
The LinLog parameter guides the way domains are split. If it is set to lin then the split is linear (i.e. the arithmetic mean of the bounds is used). If it is set to log, the split is logarithmic (i.e. the geometric mean of the bounds is used). Note that if log is used, there will be roughly the same number of representable floating point numbers on either side of the split, due to the logarithmic distribution of these numbers.
