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 , 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.

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.

Engineering Optimization ref S. S. Rao, Engineering Optimization Theory and Practice, Wiley, 2009 ref ref X. S. Yang, Engineering Optimization An Introduction with Metaheuristic Applications, Wiley, 2010 . ref is the subject which uses optimization techniques to achieve design goals in engineering and applications. ref J. N. Siddall, Optimal Engineering Design, CRC Press, 1982 . ref It is also called design optimization. Its topics include structural design e.g., pressure vessel design, welded beam design , shape optimization, topological optimization e.g., airfoil , inverse optimization, processing planning, and product designs and others. The techniques used for solving such optimization problems can be classified in three categories traditional deterministic algorithms, evolutionary algorithms or genetic algorithms, GA , and metahueristic algorithms. Traditional algorithms such as Hooke Jeeves pattern search and hill climbing are widely used for simple problems, ref P. E. Gill, W. Murray and M. H. Wright, Practical Optimization, Academic Press, London, 1981 ref while evolutionary algorithms strategies are used for more complex problems. Metaheuristic algorithms are a recent trend, and are very promising. These algorithms include particle swarm optimization , simulated annealing , differential evolution , genetic algorithms , harmony search and many others. The simple problems referred to above are problems which have a single minimum. For this case, when a minimum is found, it is also the global minimum. Other problems have more than one local minima. In this case, if a gradient method is used, a local minimum may be found, but the method may not find the global minimum. Methods which use a higher number of initial search points, such as genetic algorithms, particle swarm optimization and others have a higher probability of finding the global optimum.

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 .

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.

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.

Unreferenced date June 2008 Process optimization is the discipline of adjusting a process so as to optimize some specified set of parameters without violating some constraint. The most common goals are minimizing cost, maximizing throughput, and or efficiency. This is one of the major quantitative property quantitative tools in industrial decision making. When optimizing a process, the goal is to maximize one or more of the process specifications, while keeping all others within their constraints. Areas Fundamentally, there are three parameters that can be adjusted to affect optimal performance. They are Equipment optimization The first step is to verify that the existing equipment is being used to its fullest advantage by examining operating data to identify equipment bottlenecks. Operating procedures Operating procedures may vary widely from person to person or from shift to shift. Automation of the plant can help significantly. But automation will be of no help if the operators take control and run the plant in manual. Control optimization In a typical processing plant, such as a chemical plant or oil refinery , there are hundreds or even thousands of control loops. Each control loop is responsible for controlling one part of the process, such as maintaining a temperature, level, or flow. If the control loop is not properly designed and tuned, the process runs below its optimum. The process will be more expensive to operate, and equipment will wear out prematurely.
