ALALAWI DETERMINISTIC SOVEREIGN CORE
(ADSC-HCSP)
============================== ============================== ====================
1. SYSTEM STATE DEFINITION
============================== ============================== ====================
State = (R, N) where:
R ∈ ℤ (the computed result)
N ∈ ℤ (the input parameter i)
Valid Input Condition:
ValidState(s) = (0 ≤ s.R ≤ 20000000) ∧ (0 ≤ s.N < 1000)
============================== ============================== ====================
2. TRANSITION SYSTEM
============================== ============================== ====================
For any input value i, the transition function T : State × ℤ → State is:
T(s, i) = ( (s.R * 105) / (100 + i*2), i )
This defines the next state in the temporal evolution of the system.
============================== ============================== ====================
3. TEMPORAL PROPERTIES (LTL Formulae)
============================== ============================== ====================
Let

denote "always" (global) and ◇ denote "eventually" (future).============================== ============================== ====================
3.1 SAFETY PROPERTY (Always True)
============================== ============================== ====================
Property P1: The system never computes a negative R.
( ValidState(s) → T(s, i).R ≥ 0 )This is the exact LTL translation of:
- C: \result.R >= 0
- Coq: (transition_function current i).(R) >= 0
- TLA+: Transition(current, i).R >= 0
============================== ============================== ====================
3.2 LIVENESS PROPERTY (Always Valid Range)
============================== ============================== ====================
Property P2: The liveness check always returns 0 or 1.
( LivenessCheck(s) ∈ {0, 1} )Where:
LivenessCheck(s) = 1 if s.R > 0, and 0 otherwise.
This matches:
- C: \result == 0 || \result == 1
- TLA+: LivenessRange(s)
============================== ============================== ====================
3.3 DETERMINISM PROPERTY (Unique Next State)
============================== ============================== ====================
Property P3: Every state has exactly one possible successor.
( ∀i₁, i₂ : i₁ = i₂ → T(s, i₁) = T(s, i₂) )This ensures the system is fully deterministic.
============================== ============================== ====================
3.4 PROGRESS PROPERTY (Never Blocks)
============================== ============================== ====================
Property P4: The system can always take a step (no deadlocks).
( ∃ next_state : Transition(current, i) = next_state )Since the transition function is total, this is always true.
============================== ============================== ====================
4. FORMAL LTL PROOF THEOREMS
============================== ============================== ====================
============================== ============================== ====================
THEOREM 1: SAFETY (Corresponds to Coq: transition_safety)
============================== ============================== ====================
⊨
( ValidState(s) → T(s, i).R ≥ 0 )
( ValidState(s) → T(s, i).R ≥ 0 )Proof Steps:
1. Assumption: ValidState(s) holds.
2. From ValidState(s): s.R ≥ 0, s.R ≤ 20000000, and 0 ≤ i < 1000.
3. numerator = s.R * 105 ≥ 0.
4. denominator = 100 + i*2 ≥ 100 > 0.
5. Since numerator ≥ 0 and denominator > 0, numerator/denominator ≥ 0.
6. Therefore, T(s, i).R = numerator/denominator ≥ 0.
7. Since the condition holds for all states, it holds always:
P1.
P1.QED.
============================== ============================== ====================
THEOREM 2: LIVENESS RANGE (Corresponds to Frama-C ensures)
============================== ============================== ====================
⊨
( LivenessCheck(s) ∈ {0, 1} )
( LivenessCheck(s) ∈ {0, 1} )Proof Steps:
1. LivenessCheck(s) is defined as (s.R > 0) ? 1 : 0.
2. The conditional operator always returns either 1 or 0.
3. Therefore, LivenessCheck(s) ∈ {0, 1} holds for every state.
4. Since it holds for all states, it holds always:
P2.
P2.QED.
============================== ============================== ====================
THEOREM 3: DETERMINISM (Unique Successor)
============================== ============================== ====================
⊨
( ∀i₁, ∀i₂ : i₁ = i₂ → T(s, i₁) = T(s, i₂) )
( ∀i₁, ∀i₂ : i₁ = i₂ → T(s, i₁) = T(s, i₂) )Proof Steps:
1. For any state s and any two equal inputs i₁ = i₂:
2. T(s, i₁) = ( (s.R*105)/(100+i₁*2), i₁ )
3. T(s, i₂) = ( (s.R*105)/(100+i₂*2), i₂ )
4. Since i₁ = i₂, both components are equal.
5. Therefore, T(s, i₁) = T(s, i₂).
6. Hence, the transition is deterministic.
QED.
============================== ============================== ====================
THEOREM 4: PROGRESS (No Deadlocks)
============================== ============================== ====================
⊨
( ∃ next : next = T(s, i) )
( ∃ next : next = T(s, i) )Proof Steps:
1. T is a total function from State × ℤ to State.
2. For any state s and any input i, T(s, i) is well-defined.
3. Therefore, there always exists a next state.
4. Hence, the system never deadlocks.
QED.
