What is a hamiltonian path in a graph?
A Hamiltonian path in a graph is a path that visits every vertex exactly once. It does not need to visit every edge, only every vertex. If a Hamiltonian path exists in a graph, the graph is called a Hamiltonian graph.
What are the features of the tree?
A tree kangaroo is an arboreal-dwelling marsupial, spending much of its time feeding and resting in trees. To that end, it has numerous features quite different from those of its terrestrial cousins, and which give it more agility for its arboreal habitat.The tree kangaroo is a marsupial, giving birth to undeveloped young which must then continue its development in the mother's pouch.The tree kangaroo has a long, cylindrical non-prehensile tail, which is used as a rudder as it jumps from branch to branch in the trees.Its body size averages 66cm in length, excluding the tail, which is about as long as the body.It has larger forelegs and smaller hindlegs than kangaroos and wallabies.Its ears are short and rounded.The tree kangaroo has darker extremities, such as a black face and black paws, and is lighter on its underbelly. Its back is dark, ranging from a vivid dusky orange or rusty red to brown to dark grey, depending on the species.
What is a bipartite protein?
It's a protein with two distinct domains. Each domain might have different biochemical properties (Hydrophobic/hydrophilic) or functional role (2 enzymatic different activities or one domain required for the subcellular localization, the other one a signal transduction....)
Whats tree bears fruit every month?
The Miracle Fruit tree (Synsepalum dulcificum) is said to bear fruit almost every month. This small tropical tree produces red berries that contain a protein known as miraculin, which can temporarily alter taste perception to make sour foods taste sweet.
Is cork a type of wood?
Cork is a part of the bark on a Cork Oak Tree.
Is tree a bipartite graph?
Yes. A graph is bipartite if it contains no odd cycles. Since a tree contains no cycles at all, it is bipartite.
What is the significance of a Hamiltonian cycle in a bipartite graph and how does it impact the overall structure and connectivity of the graph?
A Hamiltonian cycle in a bipartite graph is a cycle that visits every vertex exactly once and ends at the starting vertex. It is significant because it provides a way to traverse the entire graph efficiently. Having a Hamiltonian cycle in a bipartite graph ensures that the graph is well-connected and has a strong structure, as it indicates that there is a path that visits every vertex without repeating any. This enhances the overall connectivity and accessibility of the graph, making it easier to analyze and navigate.
Show that the star graph is the only bipartiate graph which is a tree?
A star graph, call it S_k is a complete bipartite graph with one vertex in the center and k vertices around the leaves. To be a tree a graph on n vertices must be connected and have n-1 edges. We could also say it is connected and has no cycles. Now a star graph, say S_4 has 3 edges and 4 vertices and is clearly connected. It is a tree. This would be true for any S_k since they all have k vertices and k-1 edges. And Now think of K_1,k as a complete bipartite graph. We have one internal vertex and k vertices around the leaves. This gives us k+1 vertices and k edges total so it is a tree. So one way is clear. Now we would need to show that any bipartite graph other than S_1,k cannot be a tree. If we look at K_2,k which is a bipartite graph with 2 vertices on one side and k on the other,can this be a tree?
What is a biclique?
A biclique is a term used in graph theory for a special kind of bipartite graph where every vertex of the first set is connected to every vertex of the second set.
Is every tree a graph or every graph a tree?
true
How can the bipartite graph algorithm be implemented using depth-first search (DFS)?
The bipartite graph algorithm can be implemented using depth-first search (DFS) by assigning colors to each vertex as it is visited. If a vertex is visited and its neighbor has the same color, then the graph is not bipartite. If all vertices can be visited without any conflicts in colors, then the graph is bipartite.
What is the automorphism group of a complete bipartite graph?
The automorphism group of a complete bipartite graph K_n,n is (S_n x S_n) semidirect Z_2.
Meaning of bipartite?
"Bipartite" refers to a graph or network that can be divided into two sets of vertices such that all edges connect vertices from one set to the other, with no edges within the same set. A bipartite graph is also known as a bigraph.
What is the significance of perfect matching in a bipartite graph and how does it impact the overall structure and connectivity of the graph?
In a bipartite graph, a perfect matching is a set of edges that pairs each vertex in one partition with a unique vertex in the other partition. This is significant because it ensures that every vertex is connected to exactly one other vertex, maximizing the connectivity of the graph. Perfect matching plays a crucial role in determining the overall structure and connectivity of the bipartite graph, as it helps to establish relationships between different sets of vertices and can reveal important patterns or relationships within the graph.

Is tree a connected acyclic graph?
Every tree is a connected directed acylic graph.
What is a bigraph?
A bigraph is another term for a bipartite graph - in mathematics, a graph whose vertices can be divided into two disjoint sets.
