Perhaps you should try some spelling variations:
"variance optimization api python programming" » "surface optimization api python programming" (Expand search), "engine optimization api python programming" (Expand search), "value optimization api python programming" (Expand search), "variance optimization and python programming" (Expand search), "variance optimization an python programming" (Expand search), "variance optimization at python programming" (Expand search), "variance optimization manim python programming" (Expand search)
"deep convolutional and coding program" » "deep convolution and coding program" (Expand search), "deep convolutional code coding program" (Expand search), "deep conventional and coding program" (Expand search), "deep convolutional and cloning program" (Expand search), "deep convolutional and loading program" (Expand search), "deep convolutional and cooling programs" (Expand search), "deep convolutional and coping program" (Expand search), "deep convolutional and cooling program" (Expand search), "deep convolutional and cooking program" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("deep convolutional and coding program") OR ("variance optimization api python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"deep convolutional and coding program\") OR (\"variance optimization api python programming\"))".
• Removing quotes may allow a broader search: (( deep convolutional and coding program ) OR ( variance optimization api python programming )).
• Adding a wildcard symbol may retrieve word variants: (("deep convolutional and coding program") OR ("variance optimization api python programming"))*.
