Perhaps you should try some spelling variations:
methodology problems » methodology problem (Expand search), methodology process (Expand search), methodological problems (Expand search)
coupling pitons » coupling fenton's (Expand search), coupling patterns (Expand search)
action surface » active surface (Expand search), function surface (Expand search), active surfaces (Expand search)
using coupling » running coupling (Expand search), using competing (Expand search), using coupled (Expand search)
border action » border region (Expand search), under action (Expand search), border detection (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( border action surface methodology problems ) OR ( using coupling pitons python programming ))~.
