Perhaps you should try some spelling variations:
"neutrosophic graphs" » "neutrosophic graph", "neutrosophic triples", "neutrosophic rings"
"neutrosophic loops" » "neutrosophic logic", "neutrosophic sets", "neutrosophic soft"
"eutrophic graph" » "entropic graph", "neutrosophic graph"
"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 ("neutrosophic loops"))))) OR ("topic graph")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"eutrophic graph\") or (((\"neutrosophic graphs\") OR (\"neutrosophic loops\"))))) or (\"topic graph\"))".
• Removing quotes may allow a broader search: (((( eutrophic graph ) or ((( neutrosophic graphs ) OR ( neutrosophic loops ))))) or ( topic graph )).
• Adding a wildcard symbol may retrieve word variants: (((("eutrophic graph") or ((("neutrosophic graphs") OR ("neutrosophic loops"))))) or ("topic graph"))*.
