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