The algorithm runs while there is a vertex with positive excess, i.e. an active vertex in the graph. The push operation increases the flow on a residual edge, and a height function on the vertices controls through which residual edges can flow be pushed. The height function is changed by the relabel operation.
The Ford–Fulkerson method or Ford–Fulkerson algorithm (FFA) is a greedy algorithm that computes the maximum flow in a flow network.It is sometimes called a "method" instead of an "algorithm" as the approach to finding augmenting paths in a residual graph is not fully specified [1] or it is specified in several implementations with different running times. [2]
Residual Graph Initialise the residual graph by setting the preflow to values 0 and initialising the labeling. Initial saturating push is performed across all preflow arcs out of the source, s. Node a is relabeled in order to push its excess flow towards the sink, t.
In statistics, the restricted (or residual, or reduced) maximum likelihood (REML) approach is a particular form of maximum likelihood estimation that does not base estimates on a maximum likelihood fit of all the information, but instead uses a likelihood function calculated from a transformed set of data, so that nuisance parameters have no effect.

a finite directed graph G = (V, E), where V denotes the finite set of vertices and E ⊆ V×V is the set of directed edges; a source s ∈ V and a sink t ∈ V; a capacity function, which is a mapping : + denoted by c uv or c(u, v) for (u,v) ∈ E. It represents the maximum amount of flow that can pass through an edge.
