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