Perhaps you should try some spelling variations:
"based optimization in python programming" » "and optimization in python programming" (Expand search), "based optimization and python programming" (Expand search), "based optimization _ python programming" (Expand search)
"advanced oxidation in computing program" » "advanced oxidation in consulting program" (Expand search), "advanced oxidation in computer program" (Expand search), "advanced oxidation in computador program" (Expand search), "advanced oxidation and computing program" (Expand search), "advanced oxidation of computing program" (Expand search), "advanced oxidation _ computing 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: "((\"based optimization in python programming\") OR (\"advanced oxidation in computing program\"))~".
• Removing quotes may allow a broader search: (( based optimization in python programming ) OR ( advanced oxidation in computing program ))~.
• Adding a wildcard symbol may retrieve word variants: (("based optimization in python programming") OR ("advanced oxidation in computing program"))*.
