Perhaps you should try some spelling variations:
optimization algorithmss » optimization algorithms, optimisation algorithm, estimation algorithms
objective estimation » objective optimization, objective allocation
aging optimization » staffing optimization, game optimization
modified aging » 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 aging optimization algorithmss ) OR ( modified objective estimation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified aging optimization algorithmss ) OR ( modified objective estimation algorithm ))*.
