Perhaps you should try some spelling variations:
"variation functions and feeding program" » "activation functions and feeding program" (Expand search), "reaction functions and feeding program" (Expand search), "correlation functions and feeding program" (Expand search), "variation function and feeding program" (Expand search), "variation functional and feeding program" (Expand search)
"advanced simulation coding decoding program" » "advanced modulation coding decoding program" (Expand search), "advanced calculation coding decoding program" (Expand search), "advanced simulation loading decoding program" (Expand search), "advanced simulation according decoding program" (Expand search), "advanced simulation modeling decoding program" (Expand search), "advanced simulation coding welcoming program" (Expand search), "advanced simulation coding deworming program" (Expand search), "advanced simulation coding reading program" (Expand search), "advanced simulation encoding decoding program" (Expand search), "advanced simulation reading decoding program" (Expand search), "advanced simulation joint decoding 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: "((\"variation functions and feeding program\") OR (\"advanced simulation coding decoding program\"))~".
• Removing quotes may allow a broader search: (( variation functions and feeding program ) OR ( advanced simulation coding decoding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("variation functions and feeding program") OR ("advanced simulation coding decoding program"))*.
