Perhaps you should try some spelling variations:
"using computation _ precoder program" » "using computational _ precoder program" (Expand search), "using imputation _ precoder program" (Expand search), "using compilation _ precoder program" (Expand search), "using computation _ proder program" (Expand search), "using computation _ recovery program" (Expand search), "using computation _ precoce programa" (Expand search)
"using logic python python programming" » "using logic pythons python programming" (Expand search), "using logic piton python programming" (Expand search), "using logic pitons python programming" (Expand search), "using log python python programming" (Expand search), "using logistic python python programming" (Expand search), "using reologic python python programming" (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 _ precoder program\") OR (\"using logic python python programming\"))~".
• Removing quotes may allow a broader search: (( using computation _ precoder program ) OR ( using logic python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computation _ precoder program") OR ("using logic python python programming"))*.
