DAG: Total nodes are 8 but nodes b + b + c + d and b + c + d are repeated so only one time will be counted so total nodes are 8 - 2 = 6. Each repeated nodes has two edges so total edges will be 10 - 4 = 6. Hence 6 and 6 is the correct answer. Download Solution PDF. sharepoint create client id and secret

A topological order is only defined for a DAG - a graph without cycles; BBs within a function may form cycles (loops, etc). Your best approximation IMHO is to decompose the BB graph into SCCs (Strongly Connected Components).

WebDirected Acyclic Graph (DAG) coins. IOTA’s Tangle, Byteball, and Raiblocks are examples. They’re gaining a lot of traction as they seem to be a really awesome alternative to the blockchain. RaiBlocks uses a block-lattice structure.
