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