Perhaps you should try some spelling variations:
"shape optimization by python programming" » "the optimization by python programming" (Expand search), "shape optimization _ python programming" (Expand search), "shape optimization and python programming" (Expand search), "shape optimization based python programming" (Expand search), "shape optimization in python programming" (Expand search), "shape optimization of python programming" (Expand search)
"of convolutional code coding program" » "of convolutional codes coding program" (Expand search), "of convolutional and coding program" (Expand search), "of convolucional cnn coding program" (Expand search), "of conventional code coding program" (Expand search), "deep convolutional code coding program" (Expand search), "of constitutional code coding program" (Expand search), "of convolutional code cloning program" (Expand search), "of convolutional code loading program" (Expand search), "of convolutional code cooling programs" (Expand search), "of convolutional code codigo program" (Expand search), "of convolutional code according program" (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: (("of convolutional code coding program") OR ("shape optimization by python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"of convolutional code coding program\") OR (\"shape optimization by python programming\"))".
• Removing quotes may allow a broader search: (( of convolutional code coding program ) OR ( shape optimization by python programming )).
• Adding a wildcard symbol may retrieve word variants: (("of convolutional code coding program") OR ("shape optimization by python programming"))*.
