Micro-Optimizer Skill

Purpose

Apply language-specific micro-optimizations to squeeze maximum performance from competitive programming solutions.

Capabilities

• C++ optimization tricks (fast I/O, pragma optimizations)
• Python optimization (PyPy hints, list comprehensions)
• Memory layout optimization
• Vectorization opportunities
• Compiler-specific optimizations

Target Processes

• code-level-optimization
• io-optimization
• memory-optimization

Optimization Catalog

C++ Optimizations

• Fast I/O: ios_base::sync_with_stdio(false)
• Pragma optimizations: #pragma GCC optimize
• Inline expansion
• Loop unrolling
• Memory prefetching

Python Optimizations

• Use PyPy when possible
• List comprehensions over loops
• Local variable caching
• __slots__ for classes
• Avoiding global lookups

General Optimizations

• Branch prediction hints
• Cache-friendly data layout
• Avoiding unnecessary copies
• Bit manipulation tricks
