Designing cantilever retaining walls is an important task in various construction projects. The study "Optimizing cantilever retaining wall design using feasibility rule-based evolutionary algorithm developed with Visual C# .NET" aims at constructing an evolutionary-algorithm-based cantilever retaining wall design approach. Differential Evolution (DE) and the feasibility rule-based constraint-handling (FRBCH) method are integrated to achieve the research objective. A DE based software program incorporating FRBCH has been developed with Visual C# .NET to facilitate its implementation.
