An Exact Algorithm for Maximum Entropy Sampling

- Chun-Wa Ko, Jon Lee, M. Queyranne
- Mathematics, Computer Science
- Oper. Res.
- 1 August 1995

We study the experimental design problem of selecting a most informative subset, having prespecified size, from a set of correlated random variables. The problem arises in many applied domains, such… Expand

The volume of relaxed Boolean-quadric and cut polytopes

- Chun-Wa Ko, Jon Lee, E. Steingrímsson
- Mathematics, Computer Science
- Discret. Math.
- 15 January 1997

For n ⩾ 2, the boolean quadric polytope Pn is the convex hull in d:=(n+12) dimensions of the binary solutions xixj = yij, for all i < j in N ≔ 1,2,. …,n. The polytope is naturally modeled by a… Expand

Comparison of Spectral and Hadamard Bounds for D-Optimality

- Chun-Wa Ko, Jon Lee, K. Wayne
- Mathematics
- 1998

We introduce a spectral bound for D-optimal design problems, based on singular values. We compare the spectral bound to a bound based on Hadamard’s inequality which was introduced by Welch. In… Expand

The Volume of the Relaxed Boolean Quadric Polytope

- Chun-Wa Ko, Jon Lee, E. Steingrímsson
- Mathematics
- 1 November 1992

The boolean quadric polytope Pn is the convex hull in d:= (n;l) dimensions of the binary solutions of XiXj = Yij, for all i
