Perhaps you should try some spelling variations:
"neutrosophic graphs" » "neutrosophic graph", "neutrosophic triples", "neutrosophic loops"
"eutrophic graph" » "neutrosophic graph"
"entropic graph" » "entropic graphs", "centric graph", "entropic trace"
"topic graph" » "logic graph"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("eutrophic graph") OR ("neutrosophic graphs"))) OR ((("entropic graph") OR ("topic graph")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"eutrophic graph\") OR (\"neutrosophic graphs\"))) or (((\"entropic graph\") or (\"topic graph\"))))".
• Removing quotes may allow a broader search: (((( eutrophic graph ) OR ( neutrosophic graphs ))) or ((( entropic graph ) or ( topic graph )))).
• Adding a wildcard symbol may retrieve word variants: (((("eutrophic graph") OR ("neutrosophic graphs"))) or ((("entropic graph") or ("topic graph"))))*.
