Perhaps you should try some spelling variations:
"using convolutional coding planning problem" » "using convolutional codes planning problem" (Expand search), "using convolutional code planning problem" (Expand search), "using convolutional long planning problem" (Expand search), "using convolutional coding packing problem" (Expand search), "using convolutional coding planning process" (Expand search), "using convolutional coping planning problem" (Expand search), "using convolutional loading planning problem" (Expand search), "using convolutional zoning planning 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: "((\"using convolutional coding planning problem\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( using convolutional coding planning problem ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using convolutional coding planning problem") OR ("using coding python python programming"))*.
