Perhaps you should try some spelling variations:
"advanced optimization of python programming" » "variance optimization of python programming" (Expand search), "and optimization of python programming" (Expand search), "advanced oxidation of python programming" (Expand search), "advanced optimization on python programming" (Expand search), "advanced optimization _ python programming" (Expand search), "advanced optimization in python programming" (Expand search)
"and convolutional codes coding program" » "and conventional codes coding program" (Expand search), "of convolutional codes coding program" (Expand search), "_ convolutional codes coding program" (Expand search), "and convolutional codes cloning program" (Expand search), "and convolutional codes loading program" (Expand search), "and convolutional codes cooling programs" (Expand search), "and convolutional codes going program" (Expand search), "and convolutional modern coding program" (Expand search), "and convolutional clouds 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: "((\"and convolutional codes coding program\") OR (\"advanced optimization of python programming\"))~".
• Removing quotes may allow a broader search: (( and convolutional codes coding program ) OR ( advanced optimization of python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and convolutional codes coding program") OR ("advanced optimization of python programming"))*.
