Informed Search Techniques new kirti L 8.pptxKirti Verma
This document discusses various informed search techniques, including generate-and-test, hill climbing, best-first search, A* algorithm, and AO* algorithm. It provides details on the algorithms of hill climbing (simple, steepest-ascent, stochastic), best-first search, A*, and AO*, including their steps, advantages, and disadvantages. Examples are given to illustrate the workings of best-first search and A* on problems. The key differences between A* and AO* are that AO* may not find an optimal solution but uses less memory than A* and cannot get stuck in loops.
Production systems are computer programs that use rules to provide artificial intelligence. A production system consists of a set of condition-action rules, one or more knowledge databases, a rule applier that implements the control strategy, and a mechanism for resolving conflicts. There are several types of production systems including monotonic, partially commutative, non-monotonic, and commutative systems which differ in how rule application can affect later rule applications and the importance of rule application order. Monotonic systems never prevent later rule applications while non-monotonic systems can change direction as the knowledge base increases.
Breath first Search and Depth first searchKirti Verma
The document discusses graph traversal algorithms depth-first search (DFS) and breadth-first search (BFS). DFS uses a stack and traverses deeper nodes before shallower ones, outputting different traversal orders depending on the starting node. BFS uses a queue and traverses all neighbors of a node before moving to the next level, always outputting the same traversal order. Examples are given of applying DFS and BFS to a sample graph. Applications of the algorithms include computing distances, checking for cycles, and determining reachability between nodes.

This research presents the optimization techniques for reinforced concrete waffle slab design because the EC2 code cannot provide an efficient and optimum design. Waffle slab is mostly used where there is necessity to avoid column interfering the spaces or for a slab with large span or as an aesthetic purpose. Design optimization has been carried out here with MATLAB, using genetic algorithm. The objective function include the overall cost of reinforcement, concrete and formwork while the variables comprise of the depth of the rib including the topping thickness, rib width, and ribs spacing. The optimization constraints are the minimum and maximum areas of steel, flexural moment capacity, shear capacity and the geometry. The optimized cost and slab dimensions are obtained through genetic algorithm in MATLAB. The optimum steel ratio is 2.2% with minimum slab dimensions. The outcomes indicate that the design of reinforced concrete waffle slabs can be effectively carried out using the optimization process of genetic algorithm.

Welcome to the May 2025 edition of WIPAC Monthly celebrating the 14th anniversary of the WIPAC Group and WIPAC monthly.
In this edition along with the usual news from around the industry we have three great articles for your contemplation
Firstly from Michael Dooley we have a feature article about ammonia ion selective electrodes and their online applications
Secondly we have an article from myself which highlights the increasing amount of wastewater monitoring and asks "what is the overall" strategy or are we installing monitoring for the sake of monitoring
Lastly we have an article on data as a service for resilient utility operations and how it can be used effectively.
