Question
Use the screenshot (alphabet) below to code a Breadth-first search (BFS)

Transcribed Image Text:Breadth-first search
• A breadth-first search (BFS) explores
nodes nearest the root before
exploring nodes further away
For example, after searching A,
then B, then C, the search
proceeds with D, E, F, G
Node are explored in the order A B
CDEFGHIJKLM NOPQ
J
K
N
o J will be found before N

Transcribed Image Text:Breadth-first search algorithm
• Put the root node on a queue;
while (queue is not empty) {
remove a node from the queue;
if (node is a goal node) return success;
put all children of node onto the queue;
}
return failure;
