... on the build time. ANN-GA method succeeds at achieving a reasonable balance of mechanical strength and build time. Originality/value User-friendly and innovative methodology are devised for developing highly accurate ANN-GA-TOPSIS models for multi-objective optimisation. Optimum settings for three...

... and specific energy absorption (SEA) during indentation experimentally. Grey relational analysis was chosen as a multi-objective optimisation technique to optimise structural performance. Surrogate models were proposed to uphold the metamaterial’s tailorability for desired application needs. The fit...
