Perhaps you should try some spelling variations:
"based convolutional bar coding program" » "and convolutional bar coding program" (Expand search), "deep convolutional bar coding program" (Expand search), "2d convolutional bar coding program" (Expand search), "based convolutional bag coding program" (Expand search), "based convolutional and coding program" (Expand search), "based convolutional net coding program" (Expand search), "based convolutional bar cloning program" (Expand search), "based convolutional bar loading program" (Expand search), "based convolutional bar cooling programs" (Expand search), "based convolutional b coding program" (Expand search), "based convolutional lrr coding program" (Expand search), "based convolutional map coding program" (Expand search)
"advanced operators on python programming" » "valued operators on python programming" (Expand search), "advanced reactors on python programming" (Expand search), "advanced operators in python programming" (Expand search), "advanced operators of python programming" (Expand search), "advanced operators _ python programming" (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: (("based convolutional bar coding program") OR ("advanced operators on python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based convolutional bar coding program\") OR (\"advanced operators on python programming\"))".
• Removing quotes may allow a broader search: (( based convolutional bar coding program ) OR ( advanced operators on python programming )).
• Adding a wildcard symbol may retrieve word variants: (("based convolutional bar coding program") OR ("advanced operators on python programming"))*.
