Perhaps you should try some spelling variations:
"and operational semantics coding program" » "and operational practices coding program" (Expand search), "and operational semantics using program" (Expand search), "and operational semantic modeling program" (Expand search), "and operational semantics writing program" (Expand search), "and operations semantics coding program" (Expand search), "and operational semantics cloning program" (Expand search), "and operational semantics loading program" (Expand search), "and operational semantics cooling programs" (Expand search)
"using compositional data coding program" » "using computational data coding program" (Expand search), "in compositional data coding program" (Expand search), "music compositional data coding program" (Expand search), "using compositional data cloning program" (Expand search), "using compositional data loading program" (Expand search), "using compositional data cooling programs" (Expand search), "using compositional data recording program" (Expand search), "using compositional data crossing 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: "((\"and operational semantics coding program\") OR (\"using compositional data coding program\"))~".
• Removing quotes may allow a broader search: (( and operational semantics coding program ) OR ( using compositional data coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("and operational semantics coding program") OR ("using compositional data coding program"))*.
