Perhaps you should try some spelling variations:
"3d convolutional code packing problem" » "3d convolutional codes packing problem" (Expand search), "3d convolutional and packing problem" (Expand search), "3d convolucional cnn packing problem" (Expand search), "and convolutional code packing problem" (Expand search), "of convolutional code packing problem" (Expand search), "_ convolutional code packing problem" (Expand search), "3d convolutional code unpacking problem" (Expand search), "3d convolutional close packing problem" (Expand search), "3d convolutional code tracking problem" (Expand search)
"advanced location from python programming" » "advanced glycation from python programming" (Expand search), "advanced glication from python programming" (Expand search), "advanced education from python programming" (Expand search), "advanced locomotion from python programming" (Expand search), "advanced location of python programming" (Expand search), "advanced location from pathogen programming" (Expand search), "advanced location from anthony 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: "((\"3d convolutional code packing problem\") OR (\"advanced location from python programming\"))~".
• Removing quotes may allow a broader search: (( 3d convolutional code packing problem ) OR ( advanced location from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("3d convolutional code packing problem") OR ("advanced location from python programming"))*.
