## Introduction



If you are interested on LLM&Opt or AEL, you can:

1) Join LLM4Opt in Slack, 
2) Join Wechat Group, 
3) Contact us through email.

If you encounter any difficulty using the code, you can contact use thought the above or submit an [issue] 



Our implementation of **FunSearch, Deepmind** as the baseline, can be found [here](./baseline)





## A Quick Web Demo

A Quick Web Demo can be found [here](./ael/ap)





## Examples using AEL

#### Step 1: Install AEL

```bash
cd ael

pip install .
```

#### Step 2: Try Example: Greedy Algorithm for TSP

```bash
cd ael/examples/greedy_tsp

python runAEL.py
```

### More Examples using AEL (Code & Paper)

#### Combinatorial Optimization

1. Online Bin Packing, greedy heuristic, [code](./ael/examples/online_bin_packing), [paper]
2. TSP, construct heuristic, [code](./ael/examples/greedy_tsp), [paper]
3. TSP, guided local search, [code], [paper]
4. Flow Shop Scheduling Problem (FSSP), guided local search, [code], [paper]

#### Machine Learning

1. Attack, , [code](./ael/examples/L_AutoDA), [paper](https://arxiv.org/abs/2401.15335)

#### Bayesian Optimization

## Use AEL in You Application

A Step-by-step guide is provided in [here](./docs/guide/AEL_Usage.md)



## Files in ael

+ **ael.py**: main ael
+ **ec**:
  + interface_EC.py: interface for ec
  + evolution.py: evolution operators
  + management.py: population management

**Current support:**

+ **ECs:** 
  + 1i: design a new algorithm without any in-context inf.
  + e1: design an algorithm totally different from existing ones
  + e2: identify the common patterns in existing algorithms, design a new algorithm
  + m1: design a new algorithm modified from existing one
  + m2: do not design new algorithm, try different parameter settings
+ **LLMs:** 
  + API2D (https://api2d.com/) or OpenAI interface for GPT3.5 and GPT4. (Paid)
  + Huggingface interface (Free), in testing
  + Local model Llama2, in testing
  + If you want to use other LLM or if you want to use your own GPT API or local LLMs, please add your interface in ael/llm
+ population management:
  + delete worst
+ selection:
  + probability
