Perhaps you should try some spelling variations:
methodology problem » methodology proposed (Expand search), methodology project (Expand search), methodology public (Expand search)
action programming » python programming (Expand search), action programme (Expand search), con programming (Expand search)
function surface » functional surface (Expand search), functional surfaces (Expand search), function subspace (Expand search)
coder function » modern function (Expand search), power function (Expand search), over function (Expand search)
using sampling » using subsampling (Expand search), using saline (Expand search), sinus sampling (Expand search)
methods action » methods section (Expand search), methods adoption (Expand search), method reaction (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( coder function surface methodology problem ) OR ( using sampling methods action programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder function surface methodology problem ) OR ( using sampling methods action programming ))*.
