The (n2−1)-puzzle and related relocation problems

Daniel Ratner, Manfred Warmuth
1990 Journal of symbolic computation  
The studied puzzles are instances of planar relocation problems where the reachability question is polynomial but efficient relocation is NP-hard.  ...  Our research encourages the study of polynomial approximation algorithms for related robotics problems.  ...  The second author gratefully acknowledges the support of ONR grants N00014-86-K-0454 and NOOO 14-85-K-0445.  ...

Steady laminar flow through modelled vascular stenoses

M.D. Deshpande, D.P. Giddens, R.F. Mabon
1976 Journal of Biomechanics  
Numerical solutions for a number of closely related problems have been reported.  ...  The beam suffers a displacement D and refraction 6 at the wall of the test section, and as a result the point M is relocated at P (Figure 98a).  ...  The present method is restricted to p = 1 + n/2 and the type of the matrix indicated but is much simpler to implement and takes considerably less computer time. Recursion relations are assumed as  ...

Abstracts of Working Papers in Economics

1990 Abstracts of Working Papers in Economics  
The kind of problems I describe are the numerical analysis' problem of finding zeros of polynomials and the economics' problem of finding the price equilibrium.  ...  Dynamically, both problems are essentially the same; they both reduce to a search for an iterative method that converges to a zero of any function from a specified class. Rosenthal, Robert  ...  We assume that all nxn submatrices of A are non-singular and define the condition number C = C(A) to be the ratio of the largest nxn subdeterminant of A to the smallest in absolute value.  ...
