-README
------
-
-Für die Ausführung des Algorithmus wird Python 3 (empfohlene Version: 3.6.1) benötigt.
-Die Packages, die zusätzlich gebraucht werden, können der requirements.txt entnommen werden.
-(Installation kann hier einzeln oder über den Befehl: python -m pip install -r requirements.txt)
-
-Zur Ausführung bitte im Terminal in den Ordner src gehen und dort das Skript main.py starten.
-Parameter, die hierbei möglich sind:
-    -h zeigt alle Optionen an
-    -p aktiviert die Ausgabe über den Plotter als Diagramm
-    -l wird benötigt falls die Eingabe eine Liste von Problemen ist (d.h. für jobshop1.txt)
-    -i Index des Problems in der Liste (nur relevant bei -l)
-    -t setzt die Starttemperatur des Simulated Annealings
-    -s setzt die maximalen Umformungsschritte pro Generierung einer neuen Lösung
-    -a setzt die Wahrscheinlichkeit, pro Umformungsschritt auch eine Lösung zu akzeptieren, obwohl
-        noch nicht die maximalen Umformungsschritte erreicht sind
-
--t -s und -a müssen nicht alle gesetzt sein, dann wird der jeweilige Defaultwert verwendet
-Defaultwerte: max_temp = 300, max_steps = 250, accept_prob = 0.01
-
-Beispielaufruf: 
-    python .\main.py -p -l -i 2 -t 50 ..\inputdata\jobshop1.txt

-## scheduling problem defined by:
-  1. $m$ specialized machines
-  2. tasks $\tau$ of the form $(e, i)$ with $t \in \mathbb{N}$ the execution time and $i \in \{1,2,\dots,m\}$ the machine the task has to run on
-  3. $n$ jobs $T_k$ with $\forall T_k:$ linear order of tasks, with $k \in \{1,2,\dots,n\}$
-  4. Additionally, a multiset $\Omega$ of arbitrary but fixed size that contains wait states $\omega := (1, i)$ with $i \in \{1,2,\dots,m\}$ the blocked machine.
-
-The goal is to find the fastest feasible schedule $\sigma_{min}$.
-
-## evaluative function
-  - minimize the execution time of $\sigma$
-  - upper bound: largest processing time first
-  - lower bound: max sum of execution times on one machine
-
-## solutions
-  - list of tuples $(t, \tau)$ with $t \in \mathbb{N}$ the scheduled begin of $\tau$
-
-## operations
-  - $\operatorname{ins}(\omega, t)$: block a machine at time $t$ for $w$ time steps.
-  - $\operatorname{xchg}(\tau_1,\tau_2)$: exchange the position of two tasks.
-  
-Both operations require that the start times are recomputed.
-
-## neighbourhood of solution
-
-  - $\operatorname{neighbours}(\sigma) = \{x \in \Sigma | \delta(\sigma, x) \leq n\}$ with $\Sigma$ the set of all feasible schedules.
-  - $\delta$: $\delta ( \sigma )=0$, $\delta ( \operatorname{op}(x)) = \delta (x) + 1$ (ass. ins has the same penalty xchg has), $x$ either op($y$) or $\sigma$ 
-
-## constraints
-  - only schedule new $\tau$ if another $\tau$ is finished
-  - only schedule $\tau \in T_k$ that has no unscheduled predecessor in $T_k$
-  - only one task on a machine any given time
-
-## implementation in Python
-  - translate problem into list of jobs, jobs into lists of tasks, ie problem = [$T_0, T_1,\dots,T_{k-1}$], $T_i$ = [$\tau_1,\tau_2,\dots$]
-  - address tasks based on their indices, ie [0][1] is the second task of the first job.
-  - compute only one possible next solution, rate, drop/accept. $\delta$ is computed iteratively during generation
