Perhaps you should try some spelling variations:
"differential evolution algorithmss" » "differential equation algorithmss", "differential equations algorithmss", "differential convolution algorithms", "differential solution algorithm", "differential evolutionary algorithm", "differential solution algorithmss", "differential evolutionary algorithmss", "differential convolution algorithmsss"
"differential evolution algorithm" » "differential equation algorithm", "differential equations algorithm", "differential solution algorithm", "differential evolutionary algorithm", "differential convolution algorithms"

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