Perhaps you should try some spelling variations:
"and convolutional coding packing problem" » "and convolutional codes packing problem" (Expand search), "and convolutional code packing problem" (Expand search), "and convolutional long packing problem" (Expand search), "and conventional coding packing problem" (Expand search), "of convolutional coding packing problem" (Expand search), "_ convolutional coding packing problem" (Expand search), "and convolutional cutting packing problem" (Expand search), "and convolutional chain packing problem" (Expand search), "and convolutional aging packing problem" (Expand search)
"advanced application in python programming" » "advanced applications in python programming" (Expand search), "advanced glycation in python programming" (Expand search), "advanced oxidation in python programming" (Expand search), "advanced application _ 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: "((\"and convolutional coding packing problem\") OR (\"advanced application in python programming\"))~".
• Removing quotes may allow a broader search: (( and convolutional coding packing problem ) OR ( advanced application in python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and convolutional coding packing problem") OR ("advanced application in python programming"))*.
