Perhaps you should try some spelling variations:
"modeling computation in learning problem" » "modeling computational in learning problem" (Expand search), "modeling simulation in learning problem" (Expand search), "modeling notation in learning problem" (Expand search), "modeling computation in learning problems" (Expand search), "modeling computation in planning problem" (Expand search), "modeling computation in learning program" (Expand search), "modeling computation and learning problem" (Expand search), "modeling computation of learning problem" (Expand search), "modeling imputation in learning problem" (Expand search)
"using coding python python programming" » "using codigo python python programming" (Expand search), "using codigos python python programming" (Expand search), "using using python python programming" (Expand search), "using coding pythons python programming" (Expand search), "using coding piton python programming" (Expand search), "using coding pitons python programming" (Expand search), "using coping python python programming" (Expand search), "using coating python python programming" (Expand search), "using cooking 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: "((\"modeling computation in learning problem\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( modeling computation in learning problem ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("modeling computation in learning problem") OR ("using coding python python programming"))*.
