Question

What are the four major parts of iterative process

Answer 1

The four major steps or parts are-

Step 1. Estimate a reasonable starting design x(0). Set the iteration counter k=0.

Step 2. Compute a search direction d(k) at the point x(k) in the design space. This calculation generally requires a cost function value and its gradient for unconstrained problems and, in addition, constraint functions and their gradients for constrained problems.

Step 3. Check for convergence of the algorithm. If it has converged, stop; otherwise, continue.

Step 4. Calculate a positive step size αk in the direction d(k).

Step 5. Update the design as follows, set k=k+1, and go to Step 2:

We can also say-

Step One: Planning and Requirements: In this stage, map out the initial requirements, gather the related documents, and create a plan and timeline for the first iterative cycle.

Step Two: Analysis and Design: Finalize the business needs, database models, and technical requirements based on the plan. Create a working architecture, schematic, or algorithm that satisfies your requirements.

Step Three: Implementation: Develop the functionality and design required to meet the specifications.

Step Four: Testing: Identify and locate what’s not working or performing to expectations. Stakeholders, users, and product testers weigh in with their experience.

Step Five: Evaluation and Review: Compare this iteration with the requirements and expectations.
