java.lang.Object
- org.ojalgo.optimisation.integer.IntegerSolver.NodeStatistics

Enclosing class:

IntegerSolver
```
static final class IntegerSolver.NodeStatistics
extends java.lang.Object
```
When a node is determined to be a leaf - no further branching - what was the reason?

Modifier and Type	Method	Description
`(package private) boolean`	`abandoned()`	Node was created, and deferred, but then abandoned and never evaluated (sub/node problem never solved).
`(package private) long`	`countEvaluatedNodes()`
`(package private) int`	`countIntegerSolutions()`
`(package private) long`	`countSkippedNodes()`
`(package private) long`	`countTotalNodes()`
`(package private) boolean`	`exhausted()`	Node evaluated, and solution not integer, but estimate NOT possible to find better integer solution.
`(package private) boolean`	`failed()`	Failed to solve node problem because of some unexpected error – not because the node was infeasible.
`(package private) boolean`	`infeasible()`	Node problem infeasible
`(package private) boolean`	`integer()`	Integer solution found
