Perhaps you should try some spelling variations:
optimisation algorithmss » optimization algorithms, estimation algorithms, estimation algorithm
objective optimisation » objective optimization, multiobjective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
staffing optimisation » staffing optimization, static optimization
modified staffing » modified caging

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified objective optimisation algorithmss ) OR ( modified staffing optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified objective optimisation algorithmss ) OR ( modified staffing optimisation algorithm ))*.
