Perhaps you should try some spelling variations:
"modified minimal convolution algorithmss" » "modified minimal convolution algorithms", "modified minimal evolution algorithm", "modified minimal solution algorithmss", "modified thermal convolution algorithmss"
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation algorithm"

Try widening your search to All Fields.

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 minimal convolution algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective allocation algorithm") OR ("modified minimal convolution algorithmss")).
• Removing quotes may allow a broader search: (( modified objective allocation algorithm ) or ( modified minimal convolution algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective allocation algorithm") or ("modified minimal convolution algorithmss"))*.
