Perhaps you should try some spelling variations:
"advanced computation using covering problem" » "advanced computations using covering problem" (Expand search), "advanced computational using covering problem" (Expand search), "advance computational using covering problem" (Expand search), "advanced computation in covering problem" (Expand search), "advanced composition using covering problem" (Expand search), "advanced computation using routing problem" (Expand search), "advanced computation using loading problem" (Expand search), "advanced computation ring covering problem" (Expand search), "advanced computation using competing problem" (Expand search), "advanced computation using covariant problem" (Expand search)
"using model from python programming" » "ising model from python programming" (Expand search), "using modis from python programming" (Expand search), "using mobile from python programming" (Expand search), "using model from pathogen programming" (Expand search), "using model from anthony programming" (Expand search), "using models from python programming" (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: "((\"advanced computation using covering problem\") OR (\"using model from python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computation using covering problem ) OR ( using model from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation using covering problem") OR ("using model from python programming"))*.
