Theorem 4 Let [G.sup.c] be a c-edge-colored graph with no PEC closed trails, s, t [member of] V([G.sup.c]) and a non- empty subset [PSI] of V ([G.sup.c]) \{s, t}. On paths, trails and closed trails in edge-colored graphs Let <R [union] I> be any neutrosophic ...
Example 2: Fix the Error in .subset(x, j) : invalid subscript type ‘list’ This section shows how to deal with the “Error in .subset(x, j) : invalid subscript type ‘list'”. For this, we simply need to exchange the list function by the c function, i.e. we need to subset ...
