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)
"expanded description of python programming" » "emended description of python programming" (Expand search), "and description of python programming" (Expand search), "detailed description of python programming" (Expand search), "expanded description on python programming" (Expand search), "expanded description _ python programming" (Expand search), "expanded description in 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 (\"expanded description of python programming\"))~".
• Removing quotes may allow a broader search: (( _ convolutional coding coding program ) OR ( expanded description of python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional coding coding program") OR ("expanded description of python programming"))*.
