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"

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") OR ("logic 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\") or (\"logic graph\"))))))".
• Removing quotes may allow a broader search: (((( eutrophic graph ) OR ( neutrosophic graphs ))) or ((( entropic graph ) or ((( topic graph ) or ( logic graph )))))).
• Adding a wildcard symbol may retrieve word variants: (((("eutrophic graph") OR ("neutrosophic graphs"))) or ((("entropic graph") or ((("topic graph") or ("logic graph"))))))*.
