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