2. Boolean Performance Improvement :​ ​for EDA Parts
For ​Electronic Design Automation(EDA)​ or ​Architecture & Engineering Construction(AEC)​, the models are
Geometrically simple but topologically complex​.
➢ Phase-1 :​ Reimplemented/Refactored certain data structures and algorithms, which gave overall ​50% to
80% performance improvements​.
➢ Phase-2 :​ Implemented approach to understand domain specific information and using correct
operators. Now these cases started working in ​less than a minute​.
Role :​ Lead the efforts, Analyze and find new approaches and implement POCs.
Refactoring of Projection functionality:
➢ Designed and implemented the framework to make the algorithm independent of the projection
function.
➢ Refactored existing code to take algorithmic decisions instead of bug fixes.
➢ Worked on some of the limitations of the algorithm.
➢ Direct ~40 customer cases Improved.
Role :​ Analyze, Specification generation, Implementation, Testing.
Failure-Cause Reporting:
➢ On operation failure, it is ​easy to tell where the failure is but hard to tell why​.
➢ We put in theory to answer ​“Why”​ based on Causality.
➢ Designed and Implemented framework where Algorithm note complexities found during execution.
➢ On Operation failure, code will associate the complexities to failure and report them as cause for the
failure.
➢ Provides the mechanism to report operation specific failures instead of algorithm specific failures.
Role :​ Initial discussions, Analysis of cases, Implementation, Testing, Validation.
Robustify boolean algorithm for Non-Exact(fuzzy) interactions:
➢ In the current CAD world, most of the ​parts are translated from different systems​, they are complex
than the natively created parts.
➢ Such​ complex/erroneous parts introduce geometrical complexities​ like near-tangencies and
near-coincidences and fuzzy interactions.
➢ Enhanced ​certain parts of the algorithm ​to produce fuzzy but valid results​ instead of failures.
➢ Fuzziness factor is used to ​re-gain the design intent​, and used that design intent to produce the valid
intuitive output.
Role :​ Analyze cases, Idea generation, POCs, Implementation, Testing.
Self Learning:
Basic Working Knowledge of : ​MFC, C#, Databases(MySql, MS SQL, Access), ASP .NET MVC4, QT5,
JQuery, Bootstrap, HTML5, CSS, AngularJS, Wordpress, Multithreading.
