Igine this JFLAP DFA is the bi$-$directional graph

:oded by the $11\mathrm{.}4$ problem statements.

$1$

The solution will be a list of nodes for

positive instances, or $\text{'}$no$\text{'}$ for negative.

$11\mathrm{.}4$ Give a solution to each of the following problem instances:

$($a$)$ b$,$ c$,2$ c$,$ d$,1$ d$,$ e$,2$ e$,$ a$,1$ b$,$ d$,5")$

$($b$)$ TSPPATH$("$a$,$b$,3$ b$,$c$,2$ c$,$ d$,1$ d$,$e$,2$ e$,$ a$,1$ b$,$ a$,5$ ; a c$")$

$($d$)$ b$,$ c$,2$ c$,$ d$,1$ d$,$e$,2$ e$,$ a$,1$ b$,$ d$,5$ ; a d$")$
