Debug incorrect reported values of W when beta is non zero

[ppebay]

Steps to reproduce

Run full process for FWMP with alpha=beta=1.0, everything else set to defaults. This should yield the following output (only tail shown here)

Objective value:                4.00000000
Enumerated nodes:               41
Total iterations:               7623
Time (CPU seconds):             0.69
Time (Wallclock seconds):       0.73

Option for printingOptions changed from normal to all
Total time (CPU seconds):       0.69   (Wallclock seconds):       0.74


# Detailed solution:
Task 2 of load 0.5 and memory blocks [1, 3] assigned to rank 0
Task 3 of load 0.5 and memory blocks [1, 3] assigned to rank 0
Task 6 of load 1.0 and memory blocks [1, 3] assigned to rank 0
Task 7 of load 0.5 and memory blocks [1, 3] assigned to rank 0
Task 8 of load 1.5 and memory blocks [4] assigned to rank 1
Task 5 of load 2.0 and memory blocks [2] assigned to rank 2
Task 0 of load 1.0 and memory blocks [0, 2] assigned to rank 3
Task 1 of load 0.5 and memory blocks [0, 2] assigned to rank 3
Task 4 of load 0.5 and memory blocks [0, 2] assigned to rank 3

# Solution summary:
Rank 0: L = 2.5, W = 3.0, unhomed: 1
Rank 1: L = 1.5, W = 3.0, unhomed: 1
Rank 2: L = 2.0, W = 4.0, unhomed: 1
Rank 3: L = 2.0, W = 4.0, unhomed: 2
w_max = 4.0
$assignments=[3, 3, 0, 0, 3, 2, 0, 0, 1];

The bug

As per figure below, the results shown above to do not match as far as W on ranks 0 and 1 are concerned:

Specifically:

• on rank 0: V_in = 1.5, V_out = 0.5, V_max = 1.5 ==> W = 2.5+1.5 = 4.0 <> 3.0
• on rank 1: V_in = 2.5, V_out = 1.5, V_max = 2.5 ==> W = 1.5+2.5 = 4.0 <> 3.0
• on rank 2: V_in = V_out = V_max = 2.0 ==> W = 2.0+2.0 = 4.0
• on rank 3: V_in = 0.0, V_out = 2.0, V_max = 2.0 ==> W = 2.0+2.0 = 4.0
