1. Interactive Layout Design Optimization Author: Jeremy J. Michalek Presented by: Hoda Homayouni

2. Introduction o An interactive design tool that supports the designer by computationally optimizing aspects that can be modeled mathematically, while giving the designer control to make decisions influenced by subjective human judgment and intuition.

3. Design Tools o Interactive Design Tool: an object oriented representation with an interface that allows the designer to interact with the building layout optimization problem. o Automated Design Tool: uses a decomposition strategy to separate topological decisions from purely geometric decisions.

4. Topology optimization Constraints: o Overlap o Connectivity o Path o Planarity o Envelope

5. Geometric Optimization Toolbox of Constraints: o Force Inside o Prohibit Intersection o Force Minimum Intersection o Force to Edge o Bound Size o Bound Ratio o Feasible Window o Bound Build Cost o Bound Lighting
