3. Definitions Algorithms are not going to be standardized
January 2003
Definitions
Algorithms are not going to be standardized
Make sure that all necessary information and transport elements are in place to allow tools for algorithm development
Measurement does not improve system performance, ”management” does
”Management” can be done inside the algorithm itself
