Struct DpTableEntry

pub struct DpTableEntry {
    pub val: i32,
    pub children: HashSet<(usize, BitVec)>,
    pub vertex_used: Option<usize>,
}

Represents a single entry in a dynamic programming table.

Contains the value of the entry and additional information needed for retrieving the actual solution at the end of the algorithm.

Fields

val: i32

Value of the table entry. Its meaning depends on the problem to be solved.

children: HashSet<(usize, BitVec)>

References to table entries of child nodes.

vertex_used: Option<usize>

The vertex which is used for calculating the table entry.
