During the


on Wednesday July 30th


the Pieter Hemker Prize was awarded to

Houde Han, Zhongyi Huang, and R. Bruce Kellogg

for their contribution to the goal of designing the best computational algorithm for the Hemker problem. Entrants for the prize were judged based on their ability to address the following two objectives:

1. To compute numerical approximations for all values of the singular perturbation parameter within the range [1e-8,1] with a prescribed global pointwise accuracy.

2. To minimise the amount of computational work (on a desktop computer) to achieve any prescribed tolerance.

The novelty and generality of the proposed solution strategies was also considered when evaluating submissions for the prize.

Applicants for the prize submited a paper which describes the proposed method of solution and presents sample numerical output displaying the unique advantages of the proposed computational method. Sufficient evidence had to be given to support claims made by the applicant. Relevant references had also to be included.

Applicants presented a talk at the BAIL conference based on their application.
