Perhaps you should try some spelling variations:
"modified allocation optimization algorithm" » "modified allocation optimization algorithms", "modified allocation optimisation algorithm", "modified allocation estimation algorithm", "modified location optimization algorithm"
"modified adaptive evolution algorithm" » "modified adaptive solution algorithm", "modified adaptive evolutionary algorithm", "modified adaptive convolution algorithms", "modified adaptive ventilation algorithm", "modified passive 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 allocation optimization algorithm") OR ("modified adaptive evolution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified allocation optimization algorithm\") OR (\"modified adaptive evolution algorithm\"))".
• Removing quotes may allow a broader search: (( modified allocation optimization algorithm ) OR ( modified adaptive evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimization algorithm") OR ("modified adaptive evolution algorithm"))*.
