Perhaps you should try some spelling variations:
"based computation using linear programming" » "based computational using linear programming" (Expand search), "based competition using linear programming" (Expand search), "based compilation using linear programming" (Expand search), "based computations using linear programming" (Expand search), "based computation in linear programming" (Expand search), "based composition using linear programming" (Expand search)
"using modes from python programming" » "using models from python programming" (Expand search), "using modis from python programming" (Expand search), "using model from python programming" (Expand search), "using modes from pathogen programming" (Expand search), "using modes from anthony programming" (Expand search), "using codes from python programming" (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: (("based computation using linear programming") OR ("using modes from python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computation using linear programming\") OR (\"using modes from python programming\"))".
• Removing quotes may allow a broader search: (( based computation using linear programming ) OR ( using modes from python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based computation using linear programming") OR ("using modes from python programming"))*.
