Perhaps you should try some spelling variations:
"modified allocation optimization algorithms" » "modified allocation optimisation algorithm", "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified location optimization algorithms"
"modified traces evolution algorithm" » "modified traces solution algorithm", "modified traces evolutionary algorithm", "modified traces convolution algorithms", "modified sales evolution algorithm", "modified time evolution algorithm"

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

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