Adaptiveoptimization is a technique in computer science that performs dynamic recompilation of portions of a computer program program based on the current execution profile. With a simple implementation, an adaptive optimizer may simply make a trade off between Just in time compilation and interpreting instructions. At another level, adaptiveoptimization may take advantage of local data conditions to optimize away branches and to use inline expansion to decrease context switch ing. Consider a hypothetical banking application that handles transactions one after another. These transactions may be checks, deposits, and a large number of more obscure transactions. When the program executes, the actual data may consist of clearing tens of thousands of checks without processing a single deposit and without processing a single check with a fraudulent account number. An adaptive optimizer would compile assembly code to optimize for this common case. If the system then started processing tens of thousands of deposits instead, the adaptive optimizer would recompile the assembly code to optimize the new common case. This optimization may include inlining code or moving error processing code to secondary cache. Deoptimization In some systems, notably the Java Virtual Machine Citation needed date June 2011 , execution over a range of Java bytecode bytecode instructions can be provably reversed. This allows an adaptive optimizer to make risky assumptions about the code. In the above example, the optimizer may assume all transactions are checks and all account numbers are valid. When these assumptions prove incorrect, the adaptive optimizer can unwind to a valid state and then interpret the byte code instructions correctly.

An adaptive filter is a filter that self adjusts its transfer function according to an optimization algorithm driven by an error signal. Because of the complexity of the optimization algorithms, most adaptive filters are digital filter s. By way of contrast, a non adaptive filter has a static transfer function. Adaptive filters are required for some applications because some parameters of the desired processing operation for instance, the locations of reflective surfaces in a reverberant space are not known in advance. The adaptive filter uses feedback in the form of an error signal to refine its transfer function to match the changing parameters. Generally speaking, the adaptive process involves the use of a cost function , which is a criterion for optimum performance of the filter, to feed an algorithm, which determines how to modify filter transfer function to minimize the cost on the next iteration. As the power of digital signal processor s has increased, adaptive filters have become much more common and are now routinely used in devices such as mobile phones and other communication ... frequency components in the rejected range.

It has particular applications in retail , where merchants wish to identify the best combination of price and promotion marketing promotion to achieve desired sales, gross margin , inventory or market share objectives. The methods used are similar to those applied in the related field of supply chain optimization , where mathematical algorithms are applied to large databases of sales data to help Forecasting predict future outcomes . In the case of demand optimization, as well as in house sales history, there may be competitive pricing information.

Product optimization is the practice of making changes or adjustments to a product to make it more desirable. Description A product has a number of attributes. For example, a soda bottle can have different packaging variations, flavors, nutritional values. It is possible to optimize a product by making minor adjustments. Typically, the goal is to make the product more desirable and to increase marketing metrics such as Purchase Intent, Believability, Frequency of Purchase, etc. Methods Multivariate optimization is one of the most common methods for product optimization. In this method, multiple product attributes are specified and then tested with consumers. Due to complex interaction effects between different attributes for example, consumers frequently associate certain flavors with packaging colors , it is problematic to use mathematical methods, such as Conjoint Analysis, typically used in industrial process optimization. More recently companies started to adopt Evolutionary Optimization techniques for Product optimization. Evolutionary algorithms such as IDDEA are used to optimize products, concepts and messaging.

Orphan date August 2009 Hydrological optimization applies mathematical Optimization mathematics optimization techniques such as linear programming to water related problems. These problems may be for surface water , groundwater , or the combination. The work is interdisciplinary, and may be done by hydrologist s, civil engineer s, environmental engineer s, and operations research ers. Groundwater and surface water flows can be studied with hydrologic simulation . A typical program used for this work is MODFLOW . However, simulation models cannot easily help make management decisions, as simulation is descriptive. Simulation shows what would happen given a certain set of conditions. Optimization, by contrast, finds the best solution for a set of conditions. Optimization models have three parts 1 an objective, such as Minimize cost , 2 decision variables, which correspond to the options available to management, and 3 constraints, which describe the technical or physical requirements imposed on the options. To use hydrological optimization, a simulation is run to find constraint coefficients for the optimization. An engineer or manager can then add costs or benefits associated with a set of possible decisions, and solve the optimization model to find the best solution. Examples of problems solved with hydrological optimization Contaminant remediation in aquifers. The decision problem is where to locate wells, and choose a pumping rate, to minimize the cost to prevent spread of a contaminant. The constraints are associated with the hydrogeological flows. Maximizing well abstraction subject to environmental flow constraints Wagner 1995, Feyen and Gorelick 2005 .

No footnotes date October 2011 Conic optimization is a subfield of convex optimization that studies a class of structured convex optimization problems called conic optimization problems. A conic optimization problem consists of minimizing a convex function over the intersection of an affine subspace and a convex cone . The class of conic optimization problems is a subclass of convex optimization problems and it includes some of the most well known classes of convex optimization problems, namely linear programming linear and semidefinite programming . Definition Given a real number real vector space X , a convex function convex , real valued function mathematics function math f C to mathbb R math defined on a convex cone math C subset X math , and an affine subspace math mathcal H math defined by a set of affine constraints math h i x 0 math , a conic optimization problem is to find the point math x math in math C cap mathcal H math for which the number math f x math is smallest. Examples of math C math include the positive semidefinite matrices math mathbb S n math , the positive orthant math x geq mathbf 0 math for math x in mathbb R n math , and the second order cone math left x,t in mathbb R n 1 lVert x rVert leq t right math . Often math f math is a linear function, in which case the conic optimization problem reduces to a semidefinite programming semidefinite program , a linear program , and a second order cone programming second order cone program , respectively.

see also Deduplication Capacity optimization is a general term for technologies used to improve storage utilization by shrinking stored data. The primary technologies used for capacity optimization are deduplication and data compression . These solutions are delivered as software or hardware solution, integrated with existing storage systems or delivered as standalone products. Deduplication algorithms look for redundancy in sequences of bytes across comparison windows. Typically using cryptographic hash functions as identifiers of unique sequences, sequences are compared to the history of other such sequences, and where possible, the first uniquely stored version of a sequence is referenced rather than stored again. Different solutions use different methods for selecting data windows, from 4KB blocks to full file comparisons known as Single Instance Storage or SIS. Capacity optimization generally refers to the use of this kind of technology in a storage system. An example of this kind of system is the Venti file system ref http cm.bell labs.com who seanq venti fast02 talk.pdf Venti filesystem ref in the Plan9 open source OS.
