Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
near optimisation » _ optimisation, network optimization
modified water » modified male
water solution » water absorption
modified near » modified seird, modified adam

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified near optimisation algorithm ) OR ( modified water solution algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified near optimisation algorithm ) OR ( modified water solution algorithm ))*.
