## What is walk trail and path in graph theory?

An infinite walk is a sequence of edges of the same type described here, but with no first or last vertex, and a semi-infinite walk (or ray) has a first vertex but no last vertex. A trail is a walk in which all edges are distinct. A path is a trail in which all vertices (and therefore also all edges) are distinct.

## What is the difference between walk trail and path of a graph?

If the vertices in a walk are distinct, then the walk is called a path. If the edges in a walk are distinct, then the walk is called a trail. In this way, every path is a trail, but not every trail is a path.

**Is a path a walk graph theory?**

These can have repeated vertices only. It is a trail in which neither vertices nor edges are repeated i.e. if we traverse a graph such that we do not repeat a vertex and nor we repeat an edge. As path is also a trail, thus it is also an open walk.

### What is a path walk?

countable noun. A path is a long strip of ground which people walk along to get from one place to another.

### Is a path and trail the same thing?

As nouns the difference between path and trail is that path is a trail for the use of, or worn by, pedestrians while trail is the track or indication marking the route followed by something that has passed, such as the footprints of animal on land or the contrail of an airplane in the sky.

**Is walk and path same?**

A walk is a sequence of edges and vertices, where each edge’s endpoints are the two vertices adjacent to it. A path is a walk in which all vertices are distinct (except possibly the first and last). Therefore, the difference between a walk and a path is that paths cannot repeat vertices (or, it follows, edges).

## Is a walk and a path the same?

Definition: A walk consists of an alternating sequence of vertices and edges consecutive elements of which are incident, that begins and ends with a vertex. A trail is a walk without repeated edges. A path is a walk without repeated vertices.

## Is every path a walk?

The thing that stops walks from being paths is loops. So you have to show that if there is one or more loops on a walk, then you can safely remove them all and still have a walk. That walk would then be a path.

**Is every walk a trail?**

Every walk is a trail but every path is not a trail. Both paths and walks are trails.

### What is open walk in graph theory?

A walk is said to be open if the first and the last vertices are different i.e. the terminal vertices are different. A walk is said to be closed if the first and last vertices are the same. That means you start walking at a vertex and end up at the same.

### What is the difference between trail and path?

A trail is a walk with no repeated edge. A path is a walk with no repeated vertex.

**Is every path is a walk?**

## What is the difference between a path and a trail?

## What is a open trail and closed trail?

Below are some more terms you need to know. Trail is an open walk where vertices can repeat, but not edges. Path is an open walk with no repetition of vertices and edges. If you make a trail (or path) closed by coinciding the terminal vertices, then what you end up with is called a circuit (or cycle).

**Is path an open walk?**

A path is a type of open walk where neither edges nor vertices are allowed to repeat.

### What is a open walk in graph theory?

Open Walk: A walk will be known as an open walk in the graph theory if the vertices at which the walk starts and ends are different. That means for an open walk, the starting vertex and ending vertex must be different. In an open walk, the length of the walk must be more than 0.
