Perhaps you should try some spelling variations:
"variance optimization by computational program" » "surface optimization by computational program" (Expand search), "engine optimization by computational program" (Expand search), "value optimization by computational program" (Expand search), "variance optimization _ computational program" (Expand search), "variance optimization and computational program" (Expand search), "variance optimization based computational program" (Expand search)
"advanced exception in coding program" » "advanced encryption in coding program" (Expand search), "advance perceptions in coding program" (Expand search), "advanced extraction in coding program" (Expand search), "advanced exception in cloning program" (Expand search), "advanced exception in loading program" (Expand search), "advanced exception in cooling programs" (Expand search), "advanced exception on coding program" (Expand search), "advanced exception in decoding program" (Expand search), "advanced exception non coding 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: (("advanced exception in coding program") OR ("variance optimization by computational program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced exception in coding program\") OR (\"variance optimization by computational program\"))".
• Removing quotes may allow a broader search: (( advanced exception in coding program ) OR ( variance optimization by computational program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced exception in coding program") OR ("variance optimization by computational program"))*.
