Artificial Intelligence Search Algorithms and CSP Methods
Search Problem Components
- State Space: All possible configurations.
- Initial State: Starting configuration.
- Successor Function: Allowed transitions between states.
- Goal Test: Checks if the state satisfies the objective.
- Cost Function (Optional): Cost per action.
- Heuristic Function (Optional): Estimate to direct search.
- Solution: Sequence of actions from initial to goal state.
- State Space Graph: Vertices are states, edges are transitions.
- Search Tree: Tree of paths explored by the algorithm.
- Node: Data structure

Matrix Chain Multiplication
- Begin
- If N = 1: Print “Cost = 0” and Exit.
- i = 0 (Start index for splitting).
- Repeat steps 5 & 6 while i < N – 1:
- If i < N – 1:
- Cost1 = MCM(P, i + 1)
- Cost2 = MCM(P + i + 1, N – i – 1)
- CurrentCost = Cost1 + Cost2 + (P[0] * P[i + 1] * P[N])
- If i = 0: MinCost = CurrentCost; Else if CurrentCost < MinCost: MinCost = CurrentCost
- i = i + 1
- Print “Minimum cost = “, MinCost
- Exit
Job Sequencing with Deadline (Greedy)
- Start
- Sort all jobs in descending order of profit.
- Find MaxDeadline
Core Concepts of CAD Modeling and Geometric Representation
Bezier Surfaces
A Bezier surface is a parametric surface used in computer-aided design for modeling smooth and curved shapes. It is an extension of the Bezier curve into two parameters, generally represented by u and v. A Bezier surface is defined by a grid of control points that influence the shape of the surface. The surface does not necessarily pass through all control points, but its shape is controlled by them.
Bezier surfaces use Bernstein polynomials for mathematical representation. They provide

Data Structure Definition and Operations
A data structure is a systematic way of organizing, storing, and managing data in a computer so that it can be accessed, updated, and processed efficiently.
How Data is Processed in a Data Structure
Data is processed in a data structure through the following basic operations:
- Insertion: Adding new data elements into the data structure.
- Deletion: Removing existing data elements.
- Traversal: Accessing and visiting each data element to perform some operation.
- Searching:
