(Literally) Push-Button Automatic Design Optimization Technology. No need to perform DOE and/or manual sensitivity study

The Direct Global Search Technology in SmartDO eliminates manual data exploration and sensitivity study. When the setup and connection is done, automatic design optimization can be triggerred by one button. SmartDO will also graphically display important sensitivity information after the optimization is done.

Error Tolerant. Restart From The Interrupted Point

SmartDO is highly error tolerant. The user can usually restart from where the calculation is interrupted, in case of unpredicted incident or system shutdown.

SmartDO can also pass around broken/failed CAD, and the noise or nonconvergence during the CAE analysis without human judgment.

No Restriction on Number of Design Variables and/or Constraints (Successful on 170+ DVs and 132 Constraitns). Can Start From Any Infeasible Design Point

For all the solvers in SmartDO, there is no theoretical and/or coding restriction on the number of design variables and/or constraints. Powered by its Direct Global Search techniques, SmartDO can start from an infeasible design point, pushing the design into the feasible domain first, and then proceed with optimization.

Open Architecture, User Programmable with Tcl/Tk

SmartDO uses Tcl/Tk as its basic platform, which makes its architecture highly open and user programmable.

In today's competitive environment, the user programmable features allow you to differentiable with your competitor, and accumulate your know-how and experience in the script. With Tcl/Tk, the user can import add-on packages, and also develop GUI, Graphics and plotting in SmartDO.

Gradient-Based Direct Global Search

SmartDO focuses on the direct global optimization solver, which does not need much parametric study and tweaking on the solver parameter. Because of this, SmartDO has been frequently customized as the push-button expert system.

The Gradient-Based RCFDM solver uses the following techniques to achieve Direct Global Search, including

  • Combining Tunneling and Hill Climbing to jump out of local minimum.
  • Automatic response smoothing on mesh discretization and other numerical noise.
  • Automatic recognition of active constraints. Much more efficient and stable.
  • Smart Dynamic Search to automatically adjust search direction and step size.

The Robust Genetic Algorithms - GA Based Direct Global Search

The Genetic Algorithms in SmartDO can be used to solve problems not suitable for the gradient-based solver. And the Gradient-Based NLP solver provide a more efficient and accurate way of getting the optimum. These two algorithms together make SmartDO a practical and powerful optimizer.

The Robust Genetic Algorithms in SmartDO is powered by many unique technologies to achieve efficiency and stability, including

  • Adaptive Penalty Function.
  • Automatic Schema Representation.
  • Automatic Population and Generation Number Calculation.
  • Adaptive and Automatic Cross-Over Probability Calculation.
  • Absolute Descent.
