refactor adjacent_difference to permit safe in-situ operation #198

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago

Currently adjacent_difference attempts to detect in-place operation but does 
not capture all possibilities.  A better approach is to specialize the 
algorithm to gather the first element of each interval into a temporary array 
of size O(P) so blocks can safely read & write their segments without hazard.
