Perhaps you should try some spelling variations:
"using imputation from complex programing" » "using imputation from computer programing" (Expand search), "using imputation from complex programmes" (Expand search), "using imputation from complex program" (Expand search), "using mutation from complex programing" (Expand search), "testing imputation from complex programing" (Expand search), "using computational from complex programing" (Expand search), "using amputation from complex programing" (Expand search), "using computation from complex programing" (Expand search)
"using computation in coding program" » "using computational in coding program" (Expand search), "using compilation in coding program" (Expand search), "using coaptation in coding program" (Expand search), "using computation and coding program" (Expand search), "using computation of coding program" (Expand search), "using imputation in coding program" (Expand search), "using computation in cloning program" (Expand search), "using computation in loading program" (Expand search), "using computation in cooling programs" (Expand search), "using computation on coding program" (Expand search), "using computation in decoding program" (Expand search), "using computation non coding 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: "((\"using computation in coding program\") OR (\"using imputation from complex programing\"))~".
• Removing quotes may allow a broader search: (( using computation in coding program ) OR ( using imputation from complex programing ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computation in coding program") OR ("using imputation from complex programing"))*.
