Perhaps you should try some spelling variations:
"advanced computation and complexity from" » "advanced computations and complexity from" (Expand search), "advanced computational and complexity from" (Expand search), "advance computational and complexity from" (Expand search), "advanced computation of complexity from" (Expand search)
"using mobile from python programming" » "using mobilis from python programming" (Expand search), "using mobile food python programming" (Expand search), "using mobile fog python programming" (Expand search), "using mobile from pathogen programming" (Expand search), "using mobile from anthony programming" (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: "((\"advanced computation and complexity from\") OR (\"using mobile from python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computation and complexity from ) OR ( using mobile from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation and complexity from") OR ("using mobile from python programming"))*.
