+# TIG Code Submission
+
+## Submission Details
+
+* **Challenge Name:** vector_search
+* **Algorithm Name:** already_there
+* **Copyright:** 2025 ChervovNikita
+* **Identity of Submitter:** ChervovNikita
+* **Identity of Creator of Algorithmic Method:** ChervovNikita
+* **Unique Algorithm Identifier (UAI):** null
+
+## Additional Notes
+
+Statistical brute-force, about 10% faster than naive early-exit. With probability of not finding the best answer for all ements in bundle about 0.1%.
+
+Requires 100b fuel for tracks 1-3, 200b fuel for tracks 4-5.
