Perhaps you should try some spelling variations:
"numerical implementation to precoder program" » "practical implementation to precoder program" (Expand search), "numerical implementation the precoder program" (Expand search), "numerical implementation in precoder program" (Expand search), "numerical implementation _ precoder program" (Expand search), "numerical implementation to proder program" (Expand search), "numerical implementation to recovery program" (Expand search), "numerical implementation to precoce programa" (Expand search), "numerical implementation to precedent program" (Expand search)
"using codigo python python programming" » "using codigo pythons python programming" (Expand search), "using codigo piton python programming" (Expand search), "using codigo pitons python programming" (Expand search), "using indigo python python programming" (Expand search), "using coding python python programming" (Expand search), "using codium 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: "((\"numerical implementation to precoder program\") OR (\"using codigo python python programming\"))~".
• Removing quotes may allow a broader search: (( numerical implementation to precoder program ) OR ( using codigo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("numerical implementation to precoder program") OR ("using codigo python python programming"))*.
