Value

list of order hashmaps

Arguments

DAG

Directed Acyclic Graph

all_orders

list of orders

node

node

Examples

DAG = create_empty_DAG(4)
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')

# 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]]

extended_orders = extend_orders(DAG, list(order_hash), node = 'U4')
length(extended_orders)
# We can extend this order in 4 ways:
for (i in 1:length(extended_orders)){
  print(extended_orders[[i]][['U4']])
}
# We never pick U2 and U3 first, because their copula is not specified
