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