Perhaps you should try some spelling variations:
"variance optimization python computer program" » "surface optimization python computer program" (Expand search), "engine optimization python computer program" (Expand search), "value optimization python computer program" (Expand search), "variance optimization method computer program" (Expand search), "variance optimization option computer program" (Expand search), "variance optimization methods computer program" (Expand search)
"using computational code coding program" » "and computational code coding program" (Expand search), "using computational model coding program" (Expand search), "using computational cost coding program" (Expand search), "using computational models coding program" (Expand search), "using computational code cloning program" (Expand search), "using computational code loading program" (Expand search), "using computational code cooling programs" (Expand search), "using computational code codigo program" (Expand search), "using computational code according 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: "((\"using computational code coding program\") OR (\"variance optimization python computer program\"))~".
• Removing quotes may allow a broader search: (( using computational code coding program ) OR ( variance optimization python computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational code coding program") OR ("variance optimization python computer program"))*.
