Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
objective optimization » multiobjective optimization
solution algorithms » solution algorithm, evolution algorithm, convolution algorithms
exact solution » nacl solution

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 exact solution algorithms ) OR ( modified objective optimization algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified exact solution algorithms ) OR ( modified objective optimization algorithms ))*.
