Perhaps you should try some spelling variations:
"advanced optimization python python programming" » "variance optimization python python programming" (Expand search), "valued optimization python python programming" (Expand search), "and optimization python python programming" (Expand search), "advanced optimization method python programming" (Expand search), "advanced optimization option python programming" (Expand search), "advanced optimization methods python programming" (Expand search), "advanced optimization pythons python programming" (Expand search), "advanced optimization piton python programming" (Expand search), "advanced optimization pitons python programming" (Expand search)
"deep convolution and learning process" » "deep convolutional and learning process" (Expand search), "deep convection and learning process" (Expand search), "beam convolution and learning process" (Expand search), "deep evolution and learning process" (Expand search), "deep revolution and learning process" (Expand search), "deep convention and learning process" (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: "((\"deep convolution and learning process\") OR (\"advanced optimization python python programming\"))~".
• Removing quotes may allow a broader search: (( deep convolution and learning process ) OR ( advanced optimization python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("deep convolution and learning process") OR ("advanced optimization python python programming"))*.
