چکیده
A function on an algebra is congruence preserving if, for any congruence, it maps pairs of congruent elements onto elements. We show that the binary trees whose leaves are labeled by letters alphabet containing at least three letters, a if and only polynomial.

The algebra of binary search trees
We introduce a monoid structure on the set of binary search trees, by a process very similar to the construction of the plactic monoid, the Robinson-Schensted insertion being replaced by the binary search tree insertion. This leads to a new construction of the algebra of Planar Binary Trees of Loday-Ronco, defining it in the same way as Non-Commutative Symmetric Functions and Free Symmetric Fun...
متن کاملOptimal leaf ordering of complete binary trees
Ordering a set of items so as to minimize the sum of distances between consecutive elements is a fundamental optimization problem occurring in many settings. While it is NP-hard in general, it becomes polynomially solvable if the set of feasible permutations is restricted to be compatible with a tree of bounded degree. We present a new algorithm for the elementary case of ordering the n leaves ...
متن کاملEmbedding of Hypercubes into Complete Binary Trees
We estimate and characterize the edge congestion-sum measure for embeddings of hypercubes into complete binary trees. Our algorithms produce optimal values of sum of edge-congestions in linear time.
متن کاملEmbedding of Complete and Nearly Complete Binary Trees into Hypercubes
A new simple algorithm for optimal embedding of complete binary trees into hypercubes as well as a node-by-node algorithm for embedding of nearly complete binary trees into hypercubes are presented.
متن کاملEmbedding Complete Binary Trees into Star Networks
Abs t rac t . Star networks have been proposed as a possible interconnection network for massively parallel computers. In this paper we investigate embeddings of complete binary trees into star networks. Let G and H be two networks represented by simple undirected graphs. An embedding of G into H is an injective mapping f from the vertices of G into the vertices of H. The dilation of the embedd...
