Perhaps you should try some spelling variations:
"variance optimization and coding program" » "surface optimization and coding program" (Expand search), "engine optimization and coding program" (Expand search), "value optimization and coding program" (Expand search), "variance optimization and cloning program" (Expand search), "variance optimization and loading program" (Expand search), "variance optimization and cooling programs" (Expand search), "variance optimization and coping program" (Expand search), "variance optimization and cooling program" (Expand search), "variance optimization and cooking program" (Expand search)
"using combinator based coding program" » "using combination based coding program" (Expand search), "using combinatorial based coding program" (Expand search), "using combinations based coding program" (Expand search), "using compensator based coding program" (Expand search), "using combinator based cloning program" (Expand search), "using combinator based loading program" (Expand search), "using combinator based cooling programs" (Expand search), "using combinator based costing program" (Expand search), "using combinator based coating program" (Expand search), "using combinator based coatings program" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("variance optimization and coding program") OR ("using combinator based coding program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"variance optimization and coding program\") OR (\"using combinator based coding program\"))".
• Removing quotes may allow a broader search: (( variance optimization and coding program ) OR ( using combinator based coding program )).
• Adding a wildcard symbol may retrieve word variants: (("variance optimization and coding program") OR ("using combinator based coding program"))*.
