چکیده

Fixed point equations X = f (X) over ω-continuous semirings are a natural mathematical foundation of interprocedural program analysis. Generic algorithms for solving these equations are based on Kleene’s theorem, which states that the sequence 0, f (0), f (f (0)), . . . converges to the least fixed point. However, this approach is often inefficient. We report on recent work in which we extend Newton’s method, the well-known technique from numerical mathematics, to arbitrary ω-continuous semirings, and analyze its convergence speed in the real semiring.

An Extension of Newton’s Method to ω-Continuous Semirings

Fixed point equations x = F (x) over ω-continuous semirings are a natural mathematical foundation of interprocedural program analysis. Equations over the semiring of the real numbers can be solved numerically using Newton’s method. We generalize the method to any ω-continuous semiring and show that it converges faster to the least fixed point than the Kleene sequence 0, F (0), F (F (0)), . . . ...

Convergence of Newton's Method over Commutative Semirings

We give a lower bound on the speed at which Newton’s method (as defined in [5, 6]) converges over arbitrary ω-continuous commutative semirings. From this result, we deduce that Newton’s method converges within a finite number of iterations over any semiring which is “collapsed at some k ∈ N” (i.e. k = k + 1 holds) in the sense of [1]. We apply these results to (1) obtain a generalization of Par...

Student Project—Newton-Solver for Semirings

Compositional construction and manipulation of semirings. This package is motivated by static analyzers like AbsInt1. In AbsInt the complete lattice to be used for the abstract interpretation can be specified by the user by combining basic lattices, e.g., two power-set algebras on disjoint finite sets can be combined into their product lattice. In a similar fashion, we plan to give the user the...

On Fixed Point Equations over Commutative Semirings

Fixed point equations x = f(x) over ω-continuous semirings can be seen as the mathematical foundation of interprocedural program analysis. The sequence 0, f(0), f(0), . . . converges to the least fixed point μf . The convergence can be accelerated if the underlying semiring is commutative. We show that accelerations in the literature, namely Newton’s method for the arithmetic semiring [4] and a...

An Extension of Parikh's Theorem beyond Idempotence

The commutative ambiguity cambG,X of a context-free grammar G with start symbol X assigns to each Parikh vector v the number of distinct leftmost derivations yielding a word with Parikh vector v. Based on the results on the generalization of Newton’s method to ω-continuous semirings [EKL07b, EKL07a, EKL10], we show how to approximate cambG,X by means of rational formal power series, and give a ...
