This type of features is essential in many domains-e.g., automatically modify the plan length in a planning problem. E.g., we wish to write programs in a high-level language (Prolog in this case), which are capable to access ASP programs, modify their structure (by adding or removing rules), and access and reason with answer sets. – ASP solvers are independent systems interaction with other languages can be performed only through complex, low level APIs this prevents programmers from writing programs that manipulate ASP programs and answer sets as first-class citizens. These activities are important in many application domains-e.g., to express soft constraints, to support preferences when using ASP to perform planning. Nevertheless, ASP systems offer very limited capabilities for reasoning on the whole class of answer sets associated to a program-e.g., to perform selection of models according to user-defined criteria or to compare models. PROLOG Simple Prolog Planner This is one of the example programs from the textbook: Artificial Intelligence: Structures and strategies. – ASP programmers can control the computation of answer sets through the rules that they include in the logic program. Initial and Goal Situation for Blocks World Planning. In particular, it does not directly support an interactive development of programs (as in Prolog), where one can immediately explore the results of simply adding/removing rules. the grounding of an encoding relative to a problem instance as well as the search for answer sets. The process lacks any levels of interaction with the user. Most ASP systems offer only a batch approach to execution of programs-programs are completely developed, “compiled”, executed, and finally answer sets are proposed to the user.

– The development of an ASP program is viewed as a “monolithic” process. Think back to how the program is supposed to work (operators with preconditions, add and delete lists applied to some world state) try and match this to the program. Have a look at the file and make sure you understand the structure of the program. However, this is not completely satisfactory: This is the program discussed in the planning chapter of the course notes. These features allow declarative solutions in speci.c application domains. These characters and their fates raised many of the same issues now discussed in the ethics of artificial intelligence. Also, wouldnt this be a good place to mention the Prolog convention of capital letters. Blocks World in prolog steven890 (Programmer) (OP) 21 Nov 08 04:49 I try to solve the blocks world prolbem in prolog but i a, facing some difficulties ani I need your help. Artificial beings with intelligence appeared as storytelling devices in antiquity, and have been common in fiction, as in Mary Shelleys Frankenstein or Karel apeks R.U.R. Most existing ASP solvers have been extended to provide front-ends that are suitable to encode specialized forms of knowledge-e.g., weight-constraints, restricted forms of optimization, front-ends for planning and diagnosis. Its problem solving ability in the classic blocks world domain. A number of answer set solvers have been proposed in recent years, such as Smodels, DLV, Cmodels, and ASSAT.
