I have found that evolutionary optimization can handle multimodal optimization problems using a multi-objective utility function. This allows tradeoffs with competing and conflicting goals. I have used EvolOpt on many different problems during the last thirty years. I discovered this algorithm while teaching an optimization class and evolutionary algorithms class. In the neural network class, I developed an evolutionary NN that can discover a non-linear mapping from sensor data space to feature space to learn rules to guide a missile to a target. I have a C++ version I could share.

Optimizing C++ with gperftools

gperftools (Google Performance Tools) includes several tools to optimize the performance of your code:

1. CPU Profiling with gperftools

Profiling helps to identify which parts of your code take the most time.

• Collecting a Profile:

Compile your program with profiling support:

g++ -o myprogram myprogram.cpp -lprofiler

Run the program with profiling:

CPUPROFILE=/tmp/myprogram.prof ./myprogram

Analyzing the Profile:

Use pprof for analysis:

pprof --text myprogram /tmp/myprogram.prof

For visualization, use:

pprof --pdf myprogram /tmp/myprogram.prof > output.pdf

2. Using tcmalloc to Speed Up Memory Operations

tcmalloc (Thread-Caching Malloc) improves performance by managing memory more efficiently.

Installation and Usage:

nstall gperftools:

sudo apt-get install google-perftools

Link your program with tcmalloc:

g++ -o myprogram myprogram.cpp -ltcmalloc

3. Using the Heap Profiler

The heap profiler helps identify memory leaks and understand memory usage.

Collecting Heap Information:

Run your program with heap profiling:

HEAPPROFILE=/tmp/myprogram-heap ./myprogram

Analyzing the Heap:

Use pprof for analysis:

pprof --text myprogram /tmp/myprogram-heap.0001.heap

Optimizing C++ with Chrooo

Currently, there is no known tool named Chrooo associated with C++ optimization. If you meant another tool or if there was a typo, please provide more details so I can give you accurate information.

General C++ Optimization Tips

• Avoid Unnecessary Copying: Use references and pointers instead of copying large objects.
• Use Efficient Containers: For example, prefer std::vector over std::list for sequential access.
• Inline Functions: Use inline for small, frequently called functions.
• Parallelization: Use multithreading and libraries like OpenMP or Intel TBB for parallel processing.

If you have more specific questions or need assistance with these tools, please let me know.

Sorry my idea C++ optimization techniques is not C++ code optimization, but system operation in a complex environment. It's the old operations research problems.

Respected Oleh Chashyn,

Thank you for your very informative answer. The details you provided on optimizing C++ with gperftools are extremely useful.

I am also pleased to mention that KTH Royal Institute of Technology in Stockholm, Sweden, is one of my most favorite universities. I would be thrilled to collaborate with you on any projects that align with my interests. Additionally, I would appreciate any information you could share regarding funding opportunities for MS or PhD programs in computer science at KTH.
