The design of many fundamental manufacturing and circuit layout problems can be modeled as linear or nonlinear combinatorial optimization problems. All of these problems are NP hard. Very tight performance specifications for these problems (minimum area, minimum power and congestion) demand near optimal designs subject to many millions to billions of constraints and variables. Over the last six years, we have developed efficient optimization techniques that can be used to solve these problems using interior point and semidefinite programming approaches that can be solved in polynomial time. We have also developed efficient interior point solvers including warmstarting that accelerate solution times for combinatorial problems.

许多基本的制造和电路布局问题的设计可以建模为线性或非线性组合优化问题。所有这些问题都是NP难的。这些问题（最小面积、最小功率和拥塞）的非常严格的性能规范要求接近最优设计，这些设计受到数百万到数十亿的约束和变量的影响。在过去的六年中，我们已经开发出有效的优化技术，可以用来解决这些问题，使用内点和半定规划方法，可以在多项式时间内解决。我们还开发了高效的内点求解器，包括warmstarting，加快组合问题的解决时间。
