Perhaps you should try some spelling variations:
"variance optimization in coding program" » "surface optimization in coding program" (Expand search), "engine optimization in coding program" (Expand search), "value optimization in coding program" (Expand search), "variance optimization and coding program" (Expand search), "variance optimization _ coding program" (Expand search), "variance optimization in cloning program" (Expand search), "variance optimization in loading program" (Expand search), "variance optimization in cooling programs" (Expand search), "variance optimization on coding program" (Expand search), "variance optimization in decoding program" (Expand search), "variance optimization non coding program" (Expand search)
"fault localization using coding program" » "fault location using coding program" (Expand search), "and localization using coding program" (Expand search), "fault localization in coding program" (Expand search), "fault localization and coding program" (Expand search), "fault localization using cloning program" (Expand search), "fault localization using loading program" (Expand search), "fault localization using cooling programs" (Expand search), "fault localization using coping program" (Expand search), "fault localization using coating program" (Expand search), "fault localization using cooking 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: "((\"variance optimization in coding program\") OR (\"fault localization using coding program\"))~".
• Removing quotes may allow a broader search: (( variance optimization in coding program ) OR ( fault localization using coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("variance optimization in coding program") OR ("fault localization using coding program"))*.
