Perhaps you should try some spelling variations:
"variance optmization under coding program" » "variance optimization under coding program" (Expand search), "variable optimization under coding program" (Expand search), "variance estimation under coding program" (Expand search), "variance optmization power coding program" (Expand search), "variance colonization under coding program" (Expand search), "variance optmization under cloning program" (Expand search), "variance optmization under loading program" (Expand search), "variance optmization under cooling programs" (Expand search), "variance optmization under cooling program" (Expand search), "variance optmization under flooding program" (Expand search)
"advanced python programming coding program" » "advanced python programming using program" (Expand search), "advanced python programming code program" (Expand search), "advanced python programming computing program" (Expand search), "advanced method programming coding program" (Expand search), "advanced path programming coding program" (Expand search), "advanced symphony programming coding program" (Expand search), "advanced python programming cloning program" (Expand search), "advanced python programming loading program" (Expand search), "advanced python programming cooling programs" (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: "((\"variance optmization under coding program\") OR (\"advanced python programming coding program\"))~".
• Removing quotes may allow a broader search: (( variance optmization under coding program ) OR ( advanced python programming coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("variance optmization under coding program") OR ("advanced python programming coding program"))*.
