Perhaps you should try some spelling variations:
"modified delphi convolution algorithms" » "modified delphi evolution algorithm", "modified delphi solution algorithm"
"modified saline estimation algorithms" » "modified saline estimation algorithm", "modified saline optimization algorithms", "modified saline optimisation algorithm", "modified sphere estimation algorithms", "modified caging estimation algorithms", "modified male estimation algorithms", "modified passive estimation algorithms"

You may be able to get more results by adjusting your search query.

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