— Navigation is in a stack as well which means traversals can be scheduled in specific orders too

"A depth-first search starting at A, assuming that the left edges in the shown graph are chosen before right edges, and assuming the search remembers previously-visited nodes and will not repeat them (since this is a small graph), will visit the nodes in the following order: A, B, D, F, E, C, G. The edges traversed in this search form a Trémaux tree, a structure with important applications in graph theory"

— In that example, on first iteration, the caller would get this object:

{

tuple: {

original: {

aa: {},

ab: {},

ac: {}

},

search: {

aa: {},

ab: {},

ac: {}

}

},

loc: "aa",

existing: null,

isContainer: true,

isLast: false

}

— Per iteration would look similar, but the tuple will be the object being iterated and loc will be the accessor

— How is this different from depth first

— Its not

— Uhm

— Order of iteration is bfs while order of traversal is dfs

— Hmm

— Iteration is not the same process as traversal?

— No

— Hmm
