Surrogate-assisted optimization project

Wrapped up my MECH 293 final project on surrogate-assisted optimization for a 1D heterogeneous bar.

Highlights

• Trained an MLP surrogate to predict compliance and mass from Young’s moduli.
• Test RMSE: 1.27e-2 (compliance), 9.77e-3 (mass).
• Surrogate prescreening reduced FEA calls from 2000 → 50 (~40×) and found a lower compliance design.
