Perhaps you should try some spelling variations:
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"
"modified total variation algorithm" » "modified total estimation algorithm", "modified total predation algorithm", "modified total estimation algorithms", "modified global variation algorithm", "modified thermal variation algorithm", "modified ti6al4v variation 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 total variation algorithm") OR ("modified objective optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified total variation algorithm\") OR (\"modified objective optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified total variation algorithm ) OR ( modified objective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified total variation algorithm") OR ("modified objective optimisation algorithm"))*.
