Question
The diagram illustrates a project scheduling task using a directed acyclic graph (DAG), where tasks are represented as nodes and dependencies as edges. The project needs to be scheduled using three processors, following the priority list: T₈, T₉, T₅, T₇, T₆, T₂, T₄, T₁, T₃.

- **Nodes and Task Durations:**
  - T1: Duration 7
  - T2: Duration 9
  - T3: Duration 5
  - T4: Duration 10
  - T5: Duration 12
  - T6: Duration 3
  - T7: Duration 8
  - T8: Duration 6
  - T9: Duration 11
  - T10: Duration 2

- **Connections (Dependencies):**
  - T1 to T5
  - T5 to T9
  - T2 to T6
  - T6 to T8
  - T3 to T7
  - T4 to End
  - T8 to T9 and T10
  - T9 to End
  - T10 to End

- **End Node:**
  - Indicates the completion of all dependent tasks.

Each task is marked with its duration in parentheses next to its label. The goal is to assign these tasks across three processors, respecting task dependencies and the given priority list, to achieve optimal scheduling.
