Big shout-out to all the software devs who were willing to speak with us. This project could not have happened without both the open-source and commercial solver's support, and Laurent Poirrier of Bocconi University

GHF brags about delivering 1.3M meals per day. Mathematicians have a moral responsibility to speak out about the fact that 1.3M <<< 6.6M

omg thats such bullshit >:(
i recently had a fight about political ideology in an article i wrote. there, i got a lot of mileage out of pretending i didnt understand what they meant
for example, i'd say that the marked words were political (oopsie! my b!) but the rest are politically neutral facts

Numbers and data remain a big part of the propaganda, but anyone should recognize that the numbers aren't good. 58 million meals over 5 weeks makes less than 0.8 meal per day per person
Besides being a tool of forced displacement, it's also 4x too little food to avoid malnutrition

Israel has deleted data from their aid portal. Up to last May, they reported whose aid was permitted to enter. Today, this data is no longer visible
The IDF keeps publishing numbers about how much aid is coming in, but it won't say how much of that is destined for their GHF death trap

New data dropped! Since March 2nd, 32k tons of aid entered the Strip.
That's less than 5kg per person per month

In the most optimistic calculation, 350 trucks per week means an average of 830 grams per person per day. Not all of that is food
The numbers don't lie: this is continued and deliberate starvation

2007: 530 trucks per week for 1,4M people
2025: 579 trucks per week for 2,1M people, but only 5% of farmland is still usable
Israel's pattern of starving civilians is indefensible

The average number of trucks is not increasing. Recall that even COGAT's own calculations show that this is insufficient aid

In 1965, Paula Harris would find algorithmic improvements that made LP solving 50% less expensive. She was a senior mathematician in the computing group at British Petroleum
Today, 60 years later, her former colleagues still speak in awe of her intelligence
