Perhaps you should try some spelling variations:
"neutrosophic loops" » "neutrosophic logic", "neutrosophic sets", "neutrosophic soft"
"eutrophic graph" » "entropic graph", "neutrosophic graph", "neutrosophic graphs"
"topic graph" » "logic graph"

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 loops"))) OR ("topic graph"))*.
• Removing quotes may allow a broader search: (((( eutrophic graph ) or ( neutrosophic loops ))) or ( topic graph ))*.
