Using NCAR CCSM3 to Explore how Future Environmental Stresses to Plant Physiology Affect the Ocean’s Global ‘Conveyor Belt’ Runoff in terrestrial ecosystems depends upon evapotranspiration, which we have shown decreases due to the response of vegetation to elevated CO2, increased

Stochastic Sequencing and Scheduling of an Operating Room We develop algorithms for a stochastic appointment sequencing and scheduling problem with waiting time, idle time, and overtime costs. Scheduling surgeries in an operating room motivates the work. The problem is formulated

Modeling of Birth Seasonality in Canada and the Provinces Seasonality of birth has been observed in virtually all historical and contemporary populations. Exogenous type explanations for birth seasonality have been classified under two main headings: sociocultural and environmental. The role

Allocation of Overlapping Inventory in Online Advertising via MultiObjective Optimization We discuss the allocation of inventory, defined by pools of users possessing multiple characteristics, e.g. age-range, ge- ographical location, etc., to on-line advertisers who may seek some or all of

Multiobjective Optimization via Parametric Programming: Algorithms and Applications In this talk we highlight the relations between multiobjective optimization, where several conflicting objectives are simultaneously optimized subject to constraints, and parametric programming that is used to solve such problems. Solution to

A Sequential Quadratic Programming Method for Nonsmooth Optimization Algorithms for the solution of smooth, constrained optimization problems have enjoyed great successes in recent years. In particular, the framework known as sequential quadratic programming (SQP) has been studied and applied to

Strange Behaviors of Interior-point Methods for Solving Semidefinite Programming Problems in Polynomial Optimization In this talk, we show that the standard SDP solvers, such as SeDuMi and SDPA, return the significantly wrong value as the optimal value for an SDP

Primal-dual Interior Point Algorithms for LCPs with Arbitrary Matrices We have generalized some interior point algorithms (IPA) to solve LCPs in the sense of the EP-theorem. These algorithms stop in polynomial time with one of the following: (i) a solution

Full-Newton step polynomial-time methods for LO based on locally self-concordant barrier functions Recently several new search directions for interior-point methods have been introduced, based on kernel functions. Some of these function are so-called self-regular, others not. The best known iteration

A Network Optimization Model for a Candy Supply Chain We introduce a model for optimizing transportation modes (direct vs. LTL), distribution center locations, truck routing, and the timing of shipments throughout a supply chain. Our model is motivated by and
