Perhaps you should try some spelling variations:
"advanced optimization in python programming" » "variance optimization in python programming" (Expand search), "and optimization in python programming" (Expand search), "advanced oxidation in python programming" (Expand search), "advanced optimization and python programming" (Expand search), "advanced optimization _ python programming" (Expand search)
"deep convolutional ring coding program" » "deep convolutional long coding program" (Expand search), "deep convolutional coding coding program" (Expand search), "deep convolutional and coding program" (Expand search), "deep convolutional ring cloning program" (Expand search), "deep convolutional ring loading program" (Expand search), "deep convolutional ring cooling programs" (Expand search), "deep convolutional ring closing program" (Expand search), "deep convolutional using coding program" (Expand search), "deep convolutional bin1 coding program" (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 convolutional ring coding program\") OR (\"advanced optimization in python programming\"))~".
• Removing quotes may allow a broader search: (( deep convolutional ring coding program ) OR ( advanced optimization in python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("deep convolutional ring coding program") OR ("advanced optimization in python programming"))*.
