Perhaps you should try some spelling variations:
"_ convolutional coding on program" » "_ convolutional codes on program" (Expand search), "_ convolutional code on program" (Expand search), "_ convolutional long on program" (Expand search), "_ convolutional coding of program" (Expand search), "_ convolutional coding in program" (Expand search), "_ convolutional coding an program" (Expand search)
"shape optimization python python programming" » "shape optimization method python programming" (Expand search), "shape optimization option python programming" (Expand search), "shape optimization methods python programming" (Expand search), "the optimization python python programming" (Expand search), "shape optimization pythons python programming" (Expand search), "shape optimization piton python programming" (Expand search), "shape optimization pitons 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: (("_ convolutional coding on program") OR ("shape optimization python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ convolutional coding on program\") OR (\"shape optimization python python programming\"))".
• Removing quotes may allow a broader search: (( _ convolutional coding on program ) OR ( shape optimization python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional coding on program") OR ("shape optimization python python programming"))*.
