要旨:
This paper contains the first algorithm that can solve disjunctions of
constraints of
the form $\exists\SVec{y}\STI B \; [ f=0 \;\wedge\; g_1\geq
0\wedge\dots\wedge g_k\geq 0
]$ in free variables $\SVec{x}$, terminating for all cases when this results
in a numerically
well-posed problem. Here the only assumption on the terms $f, g_1,\dots, g_n$
is the
existence of a pruning function, as given by the usual constraint propagation
algorithms
or by interval evaluation. The paper discusses the application of an
implementation of
the resulting algorithm on problems from control engineering, parameter
estimation, and computational geometry.
