Perhaps you should try some spelling variations:
optimization algorithmsss » optimization algorithms, optimisation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
objective estimation » objective optimization, objective allocation
static optimization » stage optimization, stochastic optimization, staffing optimization

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified objective estimation algorithms ) OR ( modified static optimization algorithmsss ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified objective estimation algorithms ) OR ( modified static optimization algorithmsss ))".
• Adding a wildcard symbol may retrieve word variants: (( modified objective estimation algorithms ) OR ( modified static optimization algorithmsss ))*.
