Adaptive optimization 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, adaptive optimization 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.

The adaptation made is usually always? to Non functional requirement non functional characteristics rather than Functional requirement functional ones. Something of a misnomer, because the thing that adapts is the working system, rather than the more abstract Systems architecture architecture which defines the adaptability that is required of that system. Adaptive software architecture Used by programmers in relation to a program. An adaptive algorithm is an algorithm which changes its behavior based on the resources available.

A sorting algorithm falls into the adaptive sort family if it takes advantage of existing order in its input. It benefits from the presortedness in the input sequence or a limited amount of randomness disorder for various definitions of measures of disorder and sorts faster. Adaptive sorting is usually performed by modifying existing sorting algorithms. Motivation Comparison sort Comparison based sorting algorithms have traditionally dealt with achieving an optimal bound of Big O notation O n logn when dealing with time complexity . Adaptive sort takes advantage of the existing order of the input to try to achieve better times, so that the time taken by the algorithm to sort is a smoothly growing function of the size of the sequence and the disorder in the sequence. In other words, the more presorted the input is, the faster it should be sorted. This is an attractive algorithm because nearly sorted sequences are common in practice. Thus, the performance of existing sort algorithms can be improved by taking into account the existing order in the input. Note that the most worst case ... an algorithm adaptive.

Adaptive capacity is the capacity of a system to adapt if the environment where the system exists is changing. It is applied to e.g., ecology ecological systems and human social system s. As applied to ecological systems, the adaptive capacity is determined by genetic diversity of species biodiversity of particular ecosystem s heterogeneity heterogeneous ecosystem mosaics as applied to specific landscape s or biome regions. As applied to human social systems, the adaptive capacity is determined by the ability of institutions and Social network networks to learning learn , and store knowledge and experience. creativity creative flexibility in decision making and problem solving the existence of political power power structures that are responsive and consider the need s of all Project stakeholder stakeholders .

Unreferenced date December 2009 An adaptive beamformer is a beamforming system which performs adaptive spatial signal processing with an array of radar antennas or phased array in order to transmit or receive signals in different directions without having to mechanically steer the array. The main distinction between an adaptive beamformer and a conventional beamforming system is the ability of the former to adjust its performance to suit differences in its environment. A particularly important feature, in military applications, is the potential for an adaptive beamformer to reduce sensitivity to certain directions of arrival so as to counteract jamming by hostile transmissions.

Smart Antennas is multiple antenna systems having one of three structures which are single input and multiple output SIMO , multiple input and single output MISO , and multiple input and multiple output MIMO structures. MIMO is an advanced smart antenna system which has multiple transmit antennas at the transmitter and multiple receive antennas at the receiver.

An adaptive algorithm is an algorithm that changes its behavior based on the resources available. For example, stable partition , using no additional memory is O n lg n but given O n memory, it can be O n in time. As implemented by the C Standard Library , http www.sgi.com tech stl stable partition.html code stable partition code is adaptive and so it acquires as much memory as it can get up to what it would need at most and applies the algorithm using that available memory. Another example is adaptive sort , whose behaviour changes upon the presortedness of its input. Category Algorithms soft eng stub ru fr Algorithme adaptatif uk ... more details
