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