Perhaps you should try some spelling variations:
"variance optimization from python programming" » "surface optimization from python programming" (Expand search), "engine optimization from python programming" (Expand search), "value optimization from python programming" (Expand search), "variance optimization and python programming" (Expand search), "variance optimization _ python programming" (Expand search), "variance optimization by python programming" (Expand search), "variance optimization from pathogen programming" (Expand search), "variance optimization from anthony programming" (Expand search)
"_ convolutional using coding program" » "_ convolutional ring coding program" (Expand search), "_ convolutional coding coding program" (Expand search), "_ convolutional long coding program" (Expand search), "_ convolutional using cloning program" (Expand search), "_ convolutional using loading program" (Expand search), "_ convolutional using cooling programs" (Expand search), "_ convolutional using coping program" (Expand search), "_ convolutional using coating program" (Expand search), "_ convolutional using cooking 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: "((\"_ convolutional using coding program\") OR (\"variance optimization from python programming\"))~".
• Removing quotes may allow a broader search: (( _ convolutional using coding program ) OR ( variance optimization from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ convolutional using coding program") OR ("variance optimization from python programming"))*.
