Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
objective estimation » objective optimization, objective allocation
modified changing » modified caging
role algorithm » mom algorithm, our algorithm, driven algorithm
changing role » changing world, charging pile

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 objective estimation algorithms ) OR ( modified changing role algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified objective estimation algorithms ) or ( modified changing role algorithm ))*.
