Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
saline evolution » saline solution, sales evolution, time evolution
modified saline » modified caging, modified male, modified passive

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 evolution algorithm ) OR ( modified _ estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified saline evolution algorithm ) or ( modified _ estimation algorithms ))*.
