Perhaps you should try some spelling variations:
"and computational python computer program" » "and computacional python computer program" (Expand search), "and computacional vpython computer program" (Expand search), "and computacionais python computer program" (Expand search), "_ computational python computer program" (Expand search)
"surface functionals on coding program" » "surface functional on coding program" (Expand search), "surface functionalised on coding program" (Expand search), "surface functionality on coding program" (Expand search), "surface functionals in coding program" (Expand search), "surface functionals of coding program" (Expand search), "surface functions on coding program" (Expand search), "surface functionals on cloning program" (Expand search), "surface functionals on loading program" (Expand search), "surface functionals on cooling programs" (Expand search), "surface functionals non coding program" (Expand search), "surface functionals and coding program" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("and computational python computer program") OR ("surface functionals on coding program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computational python computer program\") OR (\"surface functionals on coding program\"))".
• Removing quotes may allow a broader search: (( and computational python computer program ) OR ( surface functionals on coding program )).
• Adding a wildcard symbol may retrieve word variants: (("and computational python computer program") OR ("surface functionals on coding program"))*.
