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