[r-t] Viking D Royal [was Exhausted search spaces]

[Graham John]

Don's description of his method of finding compositions illustrates
perfectly that the brute force, no intelligence, way of finding compositions
using an unrestrained composition generator is very inferior to a mixture of
applied intelligence, intuition for what might work, and directed searching
by computer to finish the job.

His method is efficient and highly effective, demonstrating that good tools
need good operators!
