Perhaps you should try some spelling variations:
"using computational workflow scheduling problems" » "using communicational workflow scheduling problems" (Expand search), "and computational workflow scheduling problems" (Expand search), "using computational workflow scheduling problem" (Expand search), "using imputational workflow scheduling problems" (Expand search), "using compilational workflow scheduling problems" (Expand search), "using coaptational workflow scheduling problems" (Expand search)
"using computation in coding program" » "using imputation 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 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 computational workflow scheduling problems\") OR (\"using computation in coding program\"))~".
• Removing quotes may allow a broader search: (( using computational workflow scheduling problems ) OR ( using computation in coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational workflow scheduling problems") OR ("using computation in coding program"))*.
