## Software consideration

----

### CORMAS by example


<img src="https://github.com/cormas/Booklet-CORMAS/raw/master/Chapters/CORMAS/chap_modelling_guide/figures/varzeaVivaFRB.gif" alt="Websocket" width="80%">



----

### CORMAS is always about the real

----

### Multiple points of views

![POV](https://github.com/cormas/Booklet-CORMAS/raw/master/Chapters/CORMAS/chap_modelling_guide/figures/multiPOVs.png)
  &#x2192; Asymmetric information to raise awareness about several viewpoints

----

### Interactive simulation

![POV](https://github.com/cormas/Booklet-CORMAS/raw/master/Chapters/CORMAS/chap_modelling_guide/figures/Kula.jpg  =550x)

----

### CORMAS and [ComMod](https://www.commod.org/)

![Simplification](https://github.com/cormas/Booklet-CORMAS/raw/master/Chapters/CORMAS/chap_modelling_guide/figures/amenajeu-rsa.JPG =500x)

<span style="font-size:22px">
    
Do not provide "ready to use" solutions, but
**Co-design** with stakeholders to get a **shared** representation. 

</span>

<span style="font-size:25px">&#x2192; Raising awareness, facilitating communication, 
    promoting coordination or mitigating conflicts </span>

### Cormas topics

![topics in 2012](https://github.com/cormas/Booklet-CORMAS/raw/master/Chapters/CORMAS/chap_modelling_guide/figures/jasssFig8.png =450x)

----

### Types of CORMAS models
From theoretical models to 
computer assisted role playing-games

### Modeling is learning

researcher / thematician = simulation dev.

----

### Modeling is learning

With a shared history, intertwined with OO !


![Simula and Smalltalk](https://parsenet.files.wordpress.com/2018/09/ooandmodelling1.png =4000x)

---

## Our values

----

### Building a shared vision


<span style="text-align:left;font-size:35px;">
    
- take care of each indivuality
- share differents points of view 
- look for a "big picture" vision

  &rarr; Promoting political spaces

</span>

![political space](https://raw.githubusercontent.com/cormas/Booklet-CORMAS/master/Chapters/CORMAS/chap_modelling_guide/figures/political_space.JPG =450x)

----

### Friendliness

- CORMAS meta-model is not prescriptive </br> &#x2192; close to stackholders description

![dear friends](https://raw.githubusercontent.com/cormas/Booklet-CORMAS/master/Chapters/CORMAS/chap_modelling_guide/figures/friendliness.JPG =450x)

----

### Decentring 

- Usually focused on stakeholders especially on their own practices.
- Put yourself in the place of the agent (you really think about what the agent does and perceives).
- Sharing and learning-by-modeling process generate empathy and mutual understanding


> Wilensky _et al._, 2006. Thinking like a Wolf, a Sheep or a Firefly

### An openWorld : transcendence

<span style="text-align:left;font-size:35px">
    
A book from an anthropologist: M. Augé, 1982, "_Génie du paganisme_". &#x2192;    The great difference between Monotheism and Polytheism : 

</span>

<span style="font-size:25px">
    
- Monotheism : God is outside is creation and believers needs to ask for world tweaking
- Polytheism : Gods are inside the world and believers can interact directly with them

</span>

----

### Transcendental CORMAS users 

<img src="https://github.com/cormas/Booklet-CORMAS/raw/master/Chapters/CORMAS/chap_modelling_guide/figures/transandence.JPG" alt="Websocket" width="50%" style="float:right">

<span style="text-align:left;font-size:40px;width:55%;">
    
CORMAS with Pharo looks like polytheism because, users can interact with the simulation just like a polytheist believer would do with his gods.

**Users** can enter slowly in Smalltalk and become an **oracle**

</span>

## Cormas Smalltalk and HPC
### (High Performance Computing)

It's now possible to connect CORMAS/Pharo with [openMole](https://openmole.org/)

### How it work?

## Courses on ABM
### MISSABMS


![MissAbms 17](https://i.imgur.com/gXCA55i.png)
3 platforms: Netlogo, Gama, Cormas

----

## Courses on ABM
### MISSABMS

- Diversity of participants,
- Afterwards, preference for UML formalization over implementation,
- UML + Smalltalk: 
    - Better understanding of OO concepts
    - Navigation between classes, 
    - Live coding into the debugger (model checking)

## To conclude

![Il buono il brutto il cattivo](https://upload.wikimedia.org/wikipedia/en/4/45/Good_the_bad_and_the_ugly_poster.jpg =400x)

### Il Buono

![Il buono](https://upload.wikimedia.org/wikipedia/it/thumb/5/50/Il_biondo.png/310px-Il_biondo.png =500x)

<span style="font-size:30px">
    
- Made by people for people
    - Smalltalk : through thick and thin (1998)
    - Object centred vision 
    - Faster learning than other languages 
- Link to real world
    - With concrete challenges: biodiversity, social equity, human/wildlife management, conflict resolution...

</span>

----

### Il Brutto 

![Il brutto](https://i.ytimg.com/vi/QCShax2Mhp0/maxresdefault.jpg =500x)

<span style="font-size:30px">

- Dirty distribution for interactive simulation
- One monster class &#x2192; work in progress
- No unit test &#x2192;  :+1:
- Quick and dirty coded and until recently without versioning &#x2192;  :+1: 

</span>

----

### Il Cattivo

![il cattivo](https://upload.wikimedia.org/wikipedia/it/thumb/6/68/Il_cattivo.png/310px-Il_cattivo.png =500x)

<span style="font-size:30px">
    
- Not (yet) GIS &#x2192; needs for spatial object manipulation
- No spatial continuity
- Limited (world size, number of agents) &#x2192; needs for optimisation

</span>


---

### Cormas Soonish :)

- Integrating with wonderful Pharo technologies
- Roassal, Maps, Spec, GT tools, DSLs

### Cormas in 10 years

<span style="font-size:30px">
    
- Tangible objects: avatar, life-size RPG  (but no 3D, no immersion glasses)
- Multi-devices : tablet, smartphone ...
- Software blocks for interactive game design
- News tools for collective design of models
- AI for hybrid simulation (when players are missing)

Focus our efforts on the **meaning** of the model (symbolic) 
more than its **aesthetic** (realistic)
