In fact, computer-generated tactics can often be more accurate and precise due to the advanced algorithms and processing power of modern computers. However, there may be instances where human intuition and creativity can lead to unexpected and innovative tactics that a computer may not have considered. Ultimately, both computer-generated and human-generated tactics have their strengths and weaknesses, and the best approach is often a combination of both. **
