Perhaps you should try some spelling variations:
"distributed estimation on coding program" » "distribution estimation on coding program" (Expand search), "distributed optimization on coding program" (Expand search), "distributed simulation on coding program" (Expand search), "distributed estimation on cloning program" (Expand search), "distributed estimation on loading program" (Expand search), "distributed estimation on cooling programs" (Expand search), "distributed estimation of coding program" (Expand search), "distributed estimation in coding program" (Expand search), "distributed estimation and coding program" (Expand search), "distributed estimation non coding program" (Expand search)
"using communication using coding program" » "nursing communication using coding program" (Expand search), "among communication using coding program" (Expand search), "esg communication using coding program" (Expand search), "using communications using coding program" (Expand search), "using communication nursing coding program" (Expand search), "using communication during coding program" (Expand search), "using communication using cloning program" (Expand search), "using communication using loading program" (Expand search), "using communication using cooling programs" (Expand search), "using communication using coping program" (Expand search), "using communication using coating program" (Expand search), "using communication 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: "((\"distributed estimation on coding program\") OR (\"using communication using coding program\"))~".
• Removing quotes may allow a broader search: (( distributed estimation on coding program ) OR ( using communication using coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("distributed estimation on coding program") OR ("using communication using coding program"))*.
