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 charging evolution algorithm" » "modified charging solution algorithm", "modified charging evolutionary algorithm", "modified charging convolution algorithms", "modified caging evolution algorithm", "modified carbon 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 charging evolution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified allocation optimization algorithm\") OR (\"modified charging evolution algorithm\"))".
• Removing quotes may allow a broader search: (( modified allocation optimization algorithm ) OR ( modified charging evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimization algorithm") OR ("modified charging evolution algorithm"))*.
