BfsInstance:var_get(+Var, ++What, -Value)
Obtain information for an individual solver problem variable Var.
- Var
- A solver problem variable for the solver associated with BfsInstance
- What
- Specification for information wanted (atom)
- Value
- Returned value of What
Description
Retrieve information about solver results related to a particular
variable, for the bfs instance BfsInstance. Fails if Var is not a
problem variable for BfsInstance. What can take one of the following
values:
- optimal_val
- Returns the floating-point solution for variable Var.
- node_val
- Returns the floating-point solution for variable Var for the
current node in the search tree of this instance.
- type
- Returns the type real or integer of Var in this instance.
Exceptions
- (6) out of range
- What is not a valid value.
