Perhaps you should try some spelling variations:
"_ convolutional coding coding program" » "_ convolutional codes coding program" (Expand search), "_ convolutional code coding program" (Expand search), "_ convolutional long coding program" (Expand search), "_ convolutional coding cloning program" (Expand search), "_ convolutional coding loading program" (Expand search), "_ convolutional coding cooling programs" (Expand search), "_ convolutional coding decoding program" (Expand search), "_ convolutional coding using program" (Expand search), "_ convolutional coding canine program" (Expand search)
"based constructs in python programming" » "based contracts in python programming" (Expand search), "based construction in python programming" (Expand search), "and constructs in python programming" (Expand search), "based constructs and python programming" (Expand search), "based constructed in python programming" (Expand search), "based constructs _ 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: "((\"_ convolutional coding coding program\") OR (\"based constructs in python programming\"))~".
• Removing quotes may allow a broader search: (( _ convolutional coding coding program ) OR ( based constructs in python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional coding coding program") OR ("based constructs in python programming"))*.
