Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
optimizer algorithms » optimized algorithms, optimized algorithm, optimization algorithms
objective estimation » objective optimization, objective allocation
write optimizer » write optimized

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 write optimizer algorithms ) OR ( modified objective estimation algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified write optimizer algorithms ) OR ( modified objective estimation algorithms ))*.
