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)
"using compilation sparse coding program" » "using computation sparse coding program" (Expand search), "using combination sparse coding program" (Expand search), "using combinations sparse coding program" (Expand search), "using population sparse coding program" (Expand search), "using compilation sparse cloning program" (Expand search), "using compilation sparse loading program" (Expand search), "using compilation sparse cooling programs" (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 (\"using compilation sparse coding program\"))~".
• Removing quotes may allow a broader search: (( variance optimization in coding program ) OR ( using compilation sparse coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("variance optimization in coding program") OR ("using compilation sparse coding program"))*.
