# Spectra
|
|
|
|
Spectra is a general purpose planning system. It extends STRIPS-style planning by allowing arbitrary DCEC and first-order formulae for state descriptions, background knowledge, and action descriptions rather than just predicates. This allows, for instance, handling domains with infinite or unbounded objects elegantly (among other things).

* Drawbacks of propositional planning (current planning systems):
|
|
* **Expressivity**: Cannot express arbitrary constraints. *“At every step make sure that no two blocks on the table have same color”*
|
|
* **Domain Size**: Scaling to large domains of arbitrary sizes poses difficulty.

## Example Problem Files
|
|
|
|
See the [example problems](https://github.com/RAIRLab/Spectra/tree/master/src/main/resources/org/rairlab/planner/problems)
|
|
|
|
## Installation
|
|
|
|
**Make sure you have Java 17 installed! While ShadowProver will, Spectra will not compile on Java 8.**
|
|
|
|
First, we need to make sure ShadowProver is installed.
|
|
|
|
```bash
|
|
git clone --recursive https://github.com/RAIRLab/ShadowProver.git
|
|
```
|
|
|
|
```bash
|
|
cd ShadowProver
|
|
mvn package
|
|
mvn install
|
|
```
|
|
|
|
Now, we can clone the Spectra repository.
|
|
|
|
```bash
|
|
git clone --recursive https://github.com/RAIRLab/Spectra.git
|
|
```
|
|
|
|
Similarly build and install the java project
|
|
|
|
```bash
|
|
cd Spectra
|
|
mvn package
|
|
mvn install
|
|
```
|
|
|
|
Now you should be able to run Spectra:
|
|
|
|
```bash
|
|
./run_spectra.sh [problem_file_path]
|
|
```
