Perhaps you should try some spelling variations:
"advanced computation in some problems" » "advanced computations in some problems" (Expand search), "advanced computational in some problems" (Expand search), "advance computational in some problems" (Expand search), "advanced computation and some problems" (Expand search), "advanced computation of some problems" (Expand search), "advanced imputation in some problems" (Expand search), "advanced computation in the problems" (Expand search), "advanced computation on some problems" (Expand search)
"using python python python programming" » "using pythons python python programming" (Expand search), "using piton python python programming" (Expand search), "using pitons python python programming" (Expand search), "usando python python python programming" (Expand search), "in python python 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 in some problems\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computation in some problems ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation in some problems") OR ("using python python python programming"))*.
