Cbc VS open-social-security

Taking a look at pulp it just seems to be a solver abstraction API and all the real work is done by solver libraries written in other languages like C++. It looks like the default solver is COIN-OR CLP/CBC, and it looks like that's written in C++: https://github.com/coin-or/Cbc/tree/master/src

Maybe I'm misunderstanding something here and it's the abstraction API causing the problems, but it seems like it's up to the solver implementation to be efficient here?

Hi! I am searching for people who have previously used COIN-OR CBC through it's C++ libraries. I am specifically going to use their lotsize variable type ( Need for Creation of a new type of variable in the CBC Solver (Bucket Variable) · Discussion #516 · coin-or/Cbc (github.com) )

To use CBC (https://github.com/coin-or/Cbc) we need to compile it. Get source code from following address instead of github, this archive include all dependencies as well which will be compiled as well (if missing)

I've looked at it a little bit, but as someone nearing retirement, it is lacking a number of features that I would like.

There are some common tricks that I don't see how to model with ProjectionLab:

1. Do your tax-deferred 401k,403b,IRA saving in a high earning job, state, then move to a low or no income tax state to do the withdrawals in retirement.

2. Retire early so there is some time before taking social security payments to do Roth Conversions. I-ORP[0] turns this into a branch and cut linear optimization problem. User Indyhou at Bogleheads[1] has built a spreadsheet that uses a solver plugin. It may be possible to build a model in CBC[2] and compile it to WASM and run it in the browser.

3. After turning 63, watch the Roth Conversions to make sure you don't trigger IRRMA medicare surcharges.

4. Are you trying to stay under income limits for ACA subsidies? It's not quite the sharp cliff that it was, but can be important for some.

5. Are you trying to balance regular income and capital gains to take advantage of the 0% cap gains rates? You've got to plan ahead on your contributions to the taxable and tax deferred accounts for this to work. Jeremy at Go Curry Cracker has written about using this to pay $0 in US Federal Income taxes[3].

6. Paying full rate for health insurance will likely get you over the 7.5% limit for tax deductions.

7. Social Security claiming strategies can be complex for married couples.

A feature that would be useful during accumulation is life insurance planning for the death of a spouse.

The death of a spouse can throw a wrench in some of the strategies since the single tax bracket is much smaller. Tax law changes can also upset highly optimized strategies. So any highly optimized strategy should also have a monte carlo simulation around a spouse dying and tax law changes to understand what disruptions are possible and maybe accept a non-optimal strategy that is better in these adverse cases.

Hi! What is your social security annuity claiming strategy? You might want to run numbers through opensocialsecurity.com . And sorry to be a downer but how does the plan look if only one of you are living? Widowhood can lead to loss of income and poverty for many (I am a widow).

Mom should check with https://opensocialsecurity.com/ before deciding when to start her benefits. Age 62 is the earliest, but she will be giving up benefit money for the rest of her life. This tool will help her see what an optimal claiming decision could be, and how much she would be giving up over her lifetime with a different decision.
