چکیده

We present ongoing work to extend proof tree preserving interpolation to inductive sequences and tree interpolants. We present an algorithm to compute tree interpolants inductively over a resolution proof. Correctness of the algorithm is justified by the concept of partial tree interpolants and the appropriate definition of a projection function for conjunctions of literals onto nodes of the tree. We observe great similarities between the interpolation rules for binary interpolation and those for tree interpolation.

Parallel Generation of t-ary Trees

A parallel algorithm for generating t-ary tree sequences in reverse B-order is presented. The algorithm generates t-ary trees by 0-1 sequences, and each 0-1 sequences is generated in constant average time O(1). The algorithm is executed on a CREW SM SIMD model, and is adaptive and cost-optimal. Prior to the discussion of the parallel algorithm a new sequential generation with O(1) average time ...

Constrained Interpolation via Cubic Hermite Splines

Introduction In industrial designing and manufacturing, it is often required to generate a smooth function approximating a given set of data which preserves certain shape properties of the data such as positivity, monotonicity, or convexity, that is, a smooth shape preserving approximation.  It is assumed here that the data is sufficiently accurate to warrant interpolation, rather than least ...
