Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
staffing optimisation » staffing optimization, static optimization
optimized algorithm » optimized algorithms, optimizer algorithms
modified staffing » modified caging
df optimized » _ optimized, _ optimize
modified df » modified _, modified adam, modified bi1

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified staffing optimisation algorithm ) OR ( modified df optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified staffing optimisation algorithm ) or ( modified df optimized algorithm ))*.
