Question 11

+1 markWritten answer

RULE BASED EXPERT SYSTEMS
A Rete Net for classification of properties is shown in the figure. The labels A1, A2, A3, ..., A10, A11, A12, A13, ..., and B1, B2, B3, B4 uniquely identify nodes in the network. When required, use the above label ordering to break ties and to enter short answers.

Run the Rete algorithm for the Working Memory shown below, the WMEs are in timestamp order. Assume that WMEs reside at appropriate Alpha nodes, and the Beta nodes point to WMEs residing in Alpha nodes.

For each WME identify its location (node label) in the Rete Net, and prepare the conflict set for the first cycle, then answer the sub-questions.

Identify the rule-data tuples in the conflict-set. Enter one rule data tuple from the conflict-set as a comma separated list in the text box: rule name followed by timestamps in ascending order.
NO SPACES, TABS, BRACKETS OR EXTRANEOUS CHARACTERS. Answer format: R9,201,202,203,204 Answers Case Sensitive : No
