McDermott: R1 rule-based computer-system configuration

What changed

Documented operational rule-based configuration of VAX orders at DEC.

Scientific scope

The record is the sole-author 1982 Artificial Intelligence paper. The larger R1/XCON project, OPS5, maintenance work, DEC personnel and later expert systems retain separate attribution; reported regular use is not a claim of error-free autonomous operation.
