This tool collects accurate data from current software so that researchers can explore new software models and metrics. IASCE also supports multiple software cost estimation models and their corresponding metrics, tractable for project management control, feedback, and learning activities. In addition, IASCE provides for the establishment of project-specific cost models and corporate metrics for the models, permits tracing of these models and metrics throughout the software life cycle via feedback and post mortem evaluation, and offers a mechanism for long-range improvements of software cost estimation. It can be tailored to a specific software development environment.<<ETX>>","PeriodicalId":265283,"journal":{"name":"Proceedings Fourth International Conference on Tools with Artificial Intelligence TAI '92","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129381312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The criterion for comparison is the distance as measured by a weighted sum of the costs of deletion, insertion, and relabel operations on tree nodes. Such comparisons may contribute to pattern recognition efforts in any field (e.g. genetics) where data can naturally be characterized by unordered trees. It is observed that the problem is NP-complete. An enumerative algorithm and several heuristics leading to approximate solutions are given. The algorithms are based on probabilistic hill climbing and bipartite matching techniques. The accuracy and time efficiency of the heuristics are evaluated by applying them to a set of trees transformed from industrial parts based on a previously proposed morphological model.<<ETX>>","PeriodicalId":265283,"journal":{"name":"Proceedings Fourth International Conference on Tools with Artificial Intelligence TAI '92","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124250571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, TAME's templates provide the building blocks and autolinks in the acquisition process.

The operation of pushing is unstable, in that once a small disturbance forces the system to abandon the stable position, the pushing operation itself makes the deviation wider. The state space is divided into 25 subregions, in each of which a control rule is specified manually. To avoid crisp division of the control space, fuzzy control logic is used. Various possibilities are summed up by membership functions. Three membership functions, one of which is made active according to the distance from the goal being near, medium, or far, are prepared.
