Branching Factor by Wikipedia

What is the branching factor?
The branching factor is the number of children at each node, or the outdegree.

What can be calculated if the value of the branching factor isn't uniform?
If the value of the branching factor isn't uniform, an average branching factor can be calculated.

What happens when algorithms that follow every branch at every node are used on a tree with a higher branching factor?
When used on a tree with a higher branching factor, algorithms that follow every branch at every node suffer from combinatorial explosion.

What does it mean when a tree has a branching factor of 10?
When a tree has a branching factor of 10, it has nodes every level down from the current position.

What can be used to cut down the branching factor?
To cut down the branching factor, a pruning algorithm can be used.

How can the average branching factor be calculated?
The average branching factor can be calculated as .
