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 model solutions algorithms" » "modified model solution algorithm", "modified model evolution algorithm", "modified model convolution algorithms", "modified nodal solution algorithms", "modified global solutions algorithms", "modified male solutions algorithms"

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 model solutions algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified allocation optimization algorithm\") OR (\"modified model solutions algorithms\"))".
• Removing quotes may allow a broader search: (( modified allocation optimization algorithm ) OR ( modified model solutions algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimization algorithm") OR ("modified model solutions algorithms"))*.
