Um dispositivo adaptativo e constituído por um dispositivo subjacente (geralmente não adaptativo), por exemplo, um autômato, uma gramática, etc., no qual se adiciona um mecanismo adaptativo que e responsável pela automodificação autônoma que caracteriza os dispositivos adaptativos. As linguagens adaptativas são instancias de dispositivos adaptativos, cujo formalismo subjacente e uma linguagem de programação. A tese tem como objetivo conceituar linguagens adaptativas de programação, descrever seus pontos essenciais e considerar os aspectos e particularidades que afetem seu desenvolvimento. A concepção de linguagens adaptativas motiva um novo estilo de programação, uma vez que a aplicação da tecnologia adaptativa sugere uma nova forma de pensar. O estilo adaptativo de programação poderá tornar-se uma alternativa viável para se obter códigos aderentes às aplicações de códigos automodificáveis. / Adaptive devices comprehend a subjacent (usually non-adaptive) device, e.g. an automaton, a grammar, etc., to which an adaptive mechanism is added which performs the self-modification operations usual in adaptive devices. Adaptive languages are special adaptive devices whose subjacent formalism is a programming language. This work defines adaptive programming languages, describes their main concepts and discusses their particular development issues. Adaptive programming languages suggest a new programming style, since applying adaptive technology induces a somewhat new way to think about programs. Such adaptive style may become an alternate way to obtain adequate code in self-modifying applications.

Software evolution and maintenance have received great attention with the steadily increasing complexity of software systems. One recent approach in this field is adaptive programming, which focuses on the evolution of large class hierarchies. Its main objectives are to manage the change in evolutionary systems and to keep costs for adaptive maintenance low. In this thesis we present our experiences with the application of adaptive programming for modeling and implementing the legal advisory system ADONIS. Unlike most other information systems, ADONIS does not simply process data but regulations. Since regulations and laws are frequently a subject to change, we have chosen this domain as the basis for our practical research on adaptive programming. / Die Evolution und Wartung von Software haben wegen der stetig wachsenden Komplexität von Softwaresystemen deutlich an Beachtung gewonnen. Ein aktueller Ansatz auf diesem Gebiet ist die adaptive Programmierung, welche sich auf die Evolution von großen Klassenhierarchien konzentriert. Ihre Hauptziele liegen darin, die wechselnden Anforderungen in evolutionären Systemen zu bewältigen und die Kosten für adaptive Wartung gering zu halten. In dieser Arbeit präsentieren wir unsere Erfahrungen mit der Anwendung der adaptiven Programmierung zur Modellierung und Implementierung des rechtlichen Beratungssystemes ADONIS. Im Gegensatz zu vielen anderen Informationssystemen verarbeitet ADONIS nicht einfach Daten, sondern Vorschriften. Aufgrunddessen, daß Vorschriften und Gesetze häufig geändert werden, haben wir diese Domäne als Grundlage für unsere praktischen Nachforschungen zum Thema adaptive Programmierung ausgewählt.
