Optimization of placement solutions for routability
Proceedings of the 50th Annual Design Automation Conference, 2013Routability has become a critical issue in VLSI design flow. To avoid producing an unroutable design, many placers [4-7] invoke global routers to get a congestion map and then move cells to reduce congestion based on this map. However, as cells move, the accuracy of the congestion map degrades, thereby affecting the effectiveness of the placer in ...

Thermodynamic Optimization of Block Placement
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 1987This paper presents the results of a systematic investigation of the thermodynamic ("simulated annealing") method applied to the placement of rectangular blocks on a chip. A new presentation of the fundamental ideas underlying this technique is proposed.

Optimal Sensor Placement: A Robust Approach
SIAM Journal on Control and Optimization, 2017We address the problem of optimally placing sensor networks for convection-diffusion processes where the convective part is perturbed. The problem is formulated as an optimal control problem where the integral Riccati equation is a constraint and the design variables are sensor locations. The objective functional involves a term associated to the trace

Port (trocar) positioning is an important component of the successful completion of laparoscopic colorectal surgery. Although individual surgeons will vary the positions, the principles are well established. The type and positioning of ports will continue to evolve as technology advances.

Optimal sensor placement for agent localization
ACM Transactions on Sensor Networks, 2006In this article we consider deploying a sensor network to help an agent navigate in an area. In particular the agent uses range measurements to the sensors to localize itself. We wish to place the sensors in order to provide optimal localization accuracy to the agent.

Sparse Sensor Placement Optimization for Classification
SIAM Journal on Applied Mathematics, 2016Choosing a limited set of sensor locations to characterize or classify a high-dimensional system is an important challenge in engineering design. Traditionally, optimizing the sensor locations involves a brute-force, combinatorial search, which is NP-hard and is computationally intractable for even moderately large problems.

Optimization of Well Placement
Journal of Energy Resources Technology, 1999Optimal placement of oil, gas or water wells is a complex problem that depends on reservoir and fluid properties, well and surface equipment specifications, as well as economic parameters. An optimization approach that enables the evaluation of all these information is presented.
