WebAlgorithm: Step 1: Place the starting node or root node into the queue. Step 2: If the queue is empty, then stop and return failure. Step 3: If the first element of the queue is our goal node, then stop and return success. Step 4: Else, remove the first element from the queue. Expand it and compute the estimated goal distance for each child. Websearch over the space of possible graphs to ﬁnd the graph that best describes the data. Often, these approaches use a search process such as a greedy, A*, or any other heuristic search (Kleinegesse et al.
