order_hash

hashmap of orders

Examples

DAG = create_empty_DAG(5)
DAG = bnlearn::set.arc(DAG, 'U1', 'U3')
DAG = bnlearn::set.arc(DAG, 'U2', 'U3')
DAG = bnlearn::set.arc(DAG, 'U1', 'U4')
DAG = bnlearn::set.arc(DAG, 'U2', 'U4')
DAG = bnlearn::set.arc(DAG, 'U3', 'U4')
DAG = bnlearn::set.arc(DAG, 'U1', 'U5')
DAG = bnlearn::set.arc(DAG, 'U2', 'U5')
DAG = bnlearn::set.arc(DAG, 'U3', 'U5')
DAG = bnlearn::set.arc(DAG, 'U4', 'U5')

# Start with empty order
order_hash = r2r::hashmap()

all_orders_3 = find_all_orders_v(DAG, v = "U3", order_hash = order_hash)
print(all_orders_3)

# Two possible choices for node 3, let's use the first
order_hash[['U3']] = all_orders_3[[1]]

all_orders_4 = find_all_orders_v(DAG, v = "U4", order_hash = order_hash)
print(all_orders_4)

# Four possible choices for node 4, let's use the third
order_hash[['U4']] = all_orders_4[[3]]

all_orders_5 = find_all_orders_v(DAG, v = "U5", order_hash = order_hash)
print(all_orders_5)

# Eight possible orders for node 5; let's use the fourth
order_hash[['U5']] = all_orders_5[[4]]
