Perhaps you should try some spelling variations:
"modified location optimization algorithms" » "modified location optimisation algorithm", "modified location estimation algorithms", "modified location estimation algorithm", "modified allocation optimization algorithms", "modified static optimization algorithms", "modified carbon optimization algorithms"
"core using methods algorithm" » "core nursing methods algorithm", "core making methods algorithm", "core counting methods algorithm", "code using methods algorithm", "care nursing methods algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("core using methods algorithm") OR ("modified location optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"core using methods algorithm\") OR (\"modified location optimization algorithms\"))".
• Removing quotes may allow a broader search: (( core using methods algorithm ) OR ( modified location optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("core using methods algorithm") OR ("modified location optimization algorithms"))*.
