We develop some foundations for a general theory of condition numbers, ill-posed problem instances, and related concepts. Justification for our formalizations is provided by results from semi-algebraic geometry, with particular reliance on the fact that decision methods for the first-order theory of the reals exist, as was proven by Tarski. © 1994 Academic Press, Inc.
