Artificial Algorithm Intelligence - Self-Adaptive Algorithm Selection & Universal Problem Solving

AAlgoI — Adaptive Algorithm Intelligence

Artificial Algorithm Intelligence — a self-adaptive system that automatically selects, executes, and learns from the best algorithm for any given problem. Combining reinforcement learning, a semantic knowledge graph, and a growing registry of 20+ algorithms across sorting, pathfinding, optimization, and machine learning domains.

---

Features

• Algorithm Selector — PPO-based RL agent picks the optimal algorithm from 20+ candidates based on problem type and data patterns
• Semantic Knowledge Graph — NetworkX-powered graph encoding relationships (Problem → Algorithm → Pattern → Constraint) that constrains RL choices and provides fallback alternatives
• Pre-Trained Model — 3-stage pipeline (supervised + RL curriculum + self-play) produces a 0.72 MB model with ~0.6 ms inference, validated on sorting, pathfinding, and domain routing (100% accuracy)
• Self-Learning — Every execution records feedback (quality, timing, success) to personalize the model via fine-tuning and bandit updates
• Algorithm Marketplace — Discover, register, benchmark, and share custom algorithms across instances
• Natural Language Interface — question_parser.py converts English descriptions into structured problem specs
• Federated Learning — Optional P2P or central-server mode for cross-instance knowledge sharing
• Rich CLI — solve, benchmark, marketplace, ml, debug, and more
• 226 Passing Tests — CI-verified test suite

Quick Start

# Install
pip install aalgoi

# Solve a problem by description
aalgoi solve "sort this list of numbers" --data 3,1,4,1,5,9,2,6,5,3,5

# Solve with explicit spec
aalgoi solve-spec --type sorting --data 5,2,8,1,9

---

Python API

After pip install aalgoi, the simplest usage is one line:

from aalgoi import solve

result = solve("sort ascending", [3, 1, 4, 1, 5])
print(result["result"])       # [1, 1, 3, 4, 5]
print(result["algorithm"])    # "insertion_sort"
print(result["time_ms"])      # 1.2
print(result["success"])      # True

The result dict always has these keys: result, algorithm, time_ms, success, answer (a human-readable summary from SmartSolver).

Sorting

from aalgoi import solve

# Basic sort
solve("sort these numbers", [5, 3, 8, 1, 2])
# → algorithm picks insertion_sort, quicksort, timsort, etc.

# With priority on speed
solve("sort as fast as possible", [5, 3, 8, 1, 2])
# → parser detects "fast" → adds objective minimize execution_time

# Large data
solve("sort this list", list(range(10000, 0, -1)))
# → RL agent picks quicksort or timsort for large reverse-sorted data

# Already-sorted data (adaptive handling)
solve("sort this", [1, 2, 3, 4, 5])
# → context_engine detects is_sorted=True, RL picks timsort (O(n))

Pathfinding

from aalgoi import solve

graph = {
    "A": {"B": 5, "C": 2},
    "B": {"D": 4},
    "C": {"B": 1, "D": 7},
    "D": {}
}

# Auto-detects PATHFINDING from data shape
result = solve("find shortest path from A to D", graph)
print(result["algorithm"])    # "dijkstra" or "a_star"
print(result["result"])       # ['A', 'C', 'B', 'D']  (shortest path)

# Explicit question
result = solve("shortest path from A to D", graph)
print(result["algorithm"])    # "dijkstra"

Optimization (Knapsack)

from aalgoi import solve

items = [
    {"value": 60, "weight": 10},
    {"value": 100, "weight": 20},
    {"value": 120, "weight": 30},
]

result = solve("maximize value within capacity 50", {
    "items": items,
    "capacity": 50
})
print(result["algorithm"])              # "greedy_knapsack"
print(result["result"]["selected"])      # [1, 2]
print(result["result"]["value"])         # 220

Using ProblemSpec

from aalgoi import solve_spec, ProblemSpec, ProblemType

spec = ProblemSpec(
    name="custom_sort",
    problem_type=ProblemType.SORTING,
)

result = solve_spec(spec, [3, 1, 2])
print(result["result"])  # [1, 2, 3]

SmartSolver (with explanation)

from aalgoi import SmartSolver

solver = SmartSolver()
result = solver.ask("sort this list quickly", [4, 2, 7, 1])

print(result["answer"])
# "Solved using timsort in 0.57ms."

print(result["algorithm"])  # "timsort"
print(result["time_ms"])    # 0.57

Explaining an algorithm

from aalgoi import explain, solve

result = solve("sort these", [3, 1, 2])
exp = explain(result)          # extracts algorithm name from result
print(exp.summary)
# "Timsort is a stable hybrid sorting algorithm..."

# Direct by name
exp = explain("quicksort")
print(exp.complexity)   # "O(n log n) average, O(n²) worst case"
print(exp.steps)        # ["Choose a pivot...", "Partition...", "Recursively apply..."]

Benchmarking

from aalgoi import benchmark, ProblemSpec, ProblemType

spec = ProblemSpec(name="test", problem_type=ProblemType.SORTING)
bm = benchmark(spec, [5, 3, 1, 4, 2])
print(bm["winner"])            # "Baseline" (or "AAlgoI")
print(bm["aalgoi_algorithm"])  # "insertion_sort"

Registering a custom algorithm

from aalgoi import UniversalSolver
from algorithms.base import Algorithm

class MySorter(Algorithm):
    def __init__(self):
        super().__init__()
        self.name = "my_sorter"
        self.time_complexity = "O(n log n)"

    def process(self, data):
        return sorted(data)

    def validate_output(self, input_data, output_data):
        return all(output_data[i] <= output_data[i+1]
                   for i in range(len(output_data)-1))

solver = UniversalSolver()
solver.register_algorithm(MySorter())

# RL agent now considers it alongside the 20 built-in algorithms
result = solver.solve(ProblemSpec(name="x", problem_type=ProblemType.SORTING), [3, 1, 2])

Quick reference — problem type detection

Each call auto-detects the problem type from the data + question text, selects the optimal algorithm via the PPO policy, executes it, stores the experience for online RL training (every 20 solves), and returns the result.

from aalgoi import solve

sorting       = solve("sort this", [3, 1, 2])
pathfinding   = solve("find path from A to B", {"A": {"B": 1}, "B": {}})
optimization  = solve("maximize value", {"items": [...], "capacity": 10})
clustering    = solve("cluster this data", [[1, 2], [5, 8], [1.5, 1.8]])
word2vec      = solve("train word2vec on medical corpus with 200 dimensions",
                      {"corpus": ["heart disease treatment", "lung cancer diagnosis"]})
image_blur    = solve("blur this image", image_array)

Pipeline Flow

1. Input — CLI command or natural language
2. Parsing — SmartSolver / question_parser extract problem type and data
3. State Encoding — 200-dimensional vector: data stats + problem type one-hot + environment info
4. RL Selection — PPO agent outputs action probabilities over 20 algorithms
5. KG Validation — Knowledge graph constrains the action to semantically valid candidates
6. Execution — Algorithm runs on the data; quality, timing, and success are recorded
7. Feedback — Results update the bandit, knowledge base, and optionally fine-tune the RL model
