What is the main problem with the chosen solution structure - Rigid type binding with low flexibility - Violation of polymorphism when processing elements - No factory method for WardrobeItem - No Adapter pattern for new optimizers - Costly operations within optimization

The main problem of the chosen solution structure is the tight coupling of types and violation of OOP principles such as polymorphism and encapsulation.

Details:

• Tight type coupling and low flexibility: if classes or methods are directly tied to specific types, it becomes difficult to extend the system or change implementations.

• Violation of polymorphism: processing elements without using interfaces or abstract classes leads to code duplication and complicates maintenance.

• Lack of a factory method for WardrobeItem: without a factory, creating objects is tightly linked to specific classes, making it difficult to add new item types.

• Absence of an Adapter pattern for new optimizers: without adapters, integrating new optimizers requires modifying existing code, violating the open/closed principle.

• High-cost operations within optimization: if heavy operations are performed inside optimization without caching or optimization, it reduces performance.

In summary: the solution structure is poorly scalable and maintainable due to the lack of abstractions and design patterns, leading to tight coupling and code duplication.
