Perhaps you should try some spelling variations:
"modified quadratic optimization algorithm" » "modified static optimization algorithm", "modified quadratic optimization algorithms", "modified quadratic optimisation algorithm", "modified quadratic estimation algorithm"
"modified objective estimation algorithmss" » "modified objective estimation algorithms", "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimization algorithmss", "modified objective allocation algorithmss"

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 quadratic optimization algorithm\") OR (\"modified objective estimation algorithmss\"))~".
• Removing quotes may allow a broader search: (( modified quadratic optimization algorithm ) OR ( modified objective estimation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified quadratic optimization algorithm") OR ("modified objective estimation algorithmss"))*.
