Perhaps you should try some spelling variations:
"advanced optimization from python programming" » "variance optimization from python programming" (Expand search), "and optimization from python programming" (Expand search), "advanced oxidation from python programming" (Expand search), "advanced optimization and python programming" (Expand search), "advanced optimization _ python programming" (Expand search), "advanced optimization by python programming" (Expand search), "advanced optimization from pathogen programming" (Expand search), "advanced optimization from anthony programming" (Expand search)
"based convention and coding program" » "basel convention and coding program" (Expand search), "based contention and coding program" (Expand search), "based conversion and coding program" (Expand search), "based conventional and coding program" (Expand search), "based convention on coding program" (Expand search), "based convention and cloning program" (Expand search), "based convention and loading program" (Expand search), "based convention and cooling programs" (Expand search), "based convention and coping program" (Expand search), "based convention and cooling program" (Expand search), "based convention and 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: "((\"based convention and coding program\") OR (\"advanced optimization from python programming\"))~".
• Removing quotes may allow a broader search: (( based convention and coding program ) OR ( advanced optimization from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based convention and coding program") OR ("advanced optimization from python programming"))*.
