Perhaps you should try some spelling variations:
multiobjective optimisation » multiobjective optimization, objective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
solutions algorithm » solution algorithm, evolution algorithm, evolutionary algorithm
bi1 solutions » mild solutions, time solutions, _ solutions
modified bi1 » modified _

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 multiobjective optimisation algorithm ) OR ( modified bi1 solutions algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified multiobjective optimisation algorithm ) OR ( modified bi1 solutions algorithm ))*.
