Monthly Reports — 2007 January
 
Murison resumed working full-time on the orbit-orbit distances paper. He created a drop-in C++ component that is a highly configurable searchable interface to the Lowell Observatory asteroids database. It also downloads the Lowell database via ftp and stuffs the data into a local database. This is part of a larger program that incorporates a new method of quickly determining asteroid-asteroid close approaches. However, the asteroids database component is self-contained and can be dropped into any program. This will allow very easy selection of all known asteroids meeting any interesting criteria on the orbital elements. A second program uses a genetic algorithm to search for stationary points of the relative distance "surface". Theory places an upper bound of 16 on the maximum possible number of such points, but extensive numerical calculations indicate that the actual limit is 12.

An attempt to apply yet another round of obnoxious security requirements to Murison's computer trashed the operating system. The least painful course of action was for the Department to purchase another computer, since the current computer was getting old and outdated anyway.

Murison performed his usual duties as Secretary of the DDA. We're ramping up for the 2007 elections and the 2007 meeting in Ann Arbor.
