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)
"base compositional data coding program" » "base composition data coding program" (Expand search), "fase composicional data coding program" (Expand search), "and compositional data coding program" (Expand search), "base compositional data cloning program" (Expand search), "base compositional data loading program" (Expand search), "base compositional data cooling programs" (Expand search), "base compositional data recording program" (Expand search), "base compositional data crossing 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: "((\"base compositional data coding program\") OR (\"variance optimization python computer program\"))~".
• Removing quotes may allow a broader search: (( base compositional data coding program ) OR ( variance optimization python computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("base compositional data coding program") OR ("variance optimization python computer program"))*.
