teems 1.0.1

Bug fix

• macOS (Docker Desktop): a second model run into the same folder within a second of the previous one fails with “cannot open sol.var”; stale solution files are now removed inside the solver container

Other changes

• ems_solve(): verbosity sets the console detail only; the full solver log always goes to model_diagnostics.txt. The default console shows the phase lines and the accuracy figures table; per-step timings, memory probes, convergence codes, the per-subinterval and updated-data accuracy summaries and the Zerodivide warnings stay in the log, and Zerodivide substitutions are reported once with a count
• The run summary shows - for a convergence code without a lowest-figures value (judged-zero results), not an empty cell
• Example scripts: the full uniform population shock object is pop_shk (it was misnamed numeraire)

teems 1.0.0

Breaking changes

• ems_solve()/solve_in_situ(): solution_method defaults to "Gragg" (was "Johansen"); "mod_midpoint" is renamed "Gragg" (it was always effectively Gragg); steps defaults by method
• laA, laD, laDi and append_args are removed as named arguments; the MA48 workspace sizes and expert solver flags are validated ... arguments
• ems_model(var_omit = ) is removed; in-TAB Omit statements are ignored with a message
• GTAP-INT is removed; GTAP-RE is replaced by version 2 on the GTAPv7.1 core
• Element names are case-insensitive on input and lowercase in all outputs
• teems checks the solver image version before solving and aborts on a missing version, a major-version mismatch or an image below 1.1.0

New functions

• ems_probe(): structural probe of a deployed model; recommends a matrix method and resources and gives a condensation verdict
• ems_RK(): Runge-Kutta solution methods (RK2, Heun, RK4, BoSha32, DoPri54) with adaptive step control

New models and data handling

• Vetted models: GTAPv7.1 (updated from GTAPv7.0), GTAP-AEZ, GTAP-E, GTAP-EP (GTAP-Power)
• ems_data() loads a single-HAR database (par_input/set_input optional)
• ems_data(par_weights = ): "value" (default, the FlexAgg rule) or "share" weights for parameter aggregation, overridable per parameter
• Closure swaps were applied ins-before-outs, rejecting valid sequences; two swaps in on one tuple wrote duplicate closure entries
• ems_scenario_shock(partial = TRUE): a scenario may cover only some of the aggregated tuples; the uncovered ones keep a zero change, and an aggregated tuple covered in part stops the deployment by name

Solving

• solution_method gains "Euler" and the Runge-Kutta family; Euler and Gragg accept a single step count (no extrapolation), and Gragg accepts all-odd counts
• Condensation: in-TAB Substitute/Backsolve statements and ems_model(backsolve = , ignore_condense = )
• ems_solve() gains n_threads, precision = "double" and verbosity
• Run-mode switches (assertions, range tests) are set with ems_option_set()
• Coefficients are read from the solver’s binary dump at full precision (previously CSVs with six fixed decimals); ems_deploy(write_coefficients = TRUE) restores the CSVs
• Solver failures are reported by class (resource, size, model specification, interface) instead of a generic exit status

TABLO coverage

• Set expressions, conditional set builders, $POS, Mapping, levels variables and equations, Complementarity, PostSim, IF terms in formulas and equations, Read (IfHeaderExists)
• Malformed TABs abort by name at model load instead of inside the solver

Bug fixes affecting results

• ems_uniform_shock() on a one-index variable restricted to an element or subset shocked the wrong elements (element 0 / the first n elements of the full set) (solver 1.1.0)
• DPSM (all GTAP models) was summed over aggregated regions, so an aggregated region held the number of subsumed original GTAP regions instead of 1
• GTAPv7: the scalar pxwwld was dropped from E_c1_cr, E_cnttotr and E_cntpinv because the solver did not recognize a variable followed by a closing bracket (solver 1.1.0)
• DBBD solves left residuals that multi-step runs accumulated; every DBBD solve now takes one refinement step (solver 1.1.0)
• Data rounding used fixed decimals, writing small values (below 5e-7) as 0; values now keep ndigits significant digits
• Whole-valued Real data at or above 2^31 was written as empty fields
• Sets read from a header, and explicit set lists, were written in alphabetical rather than file/declaration order, misaligning data indexed over unions and changing $POS arithmetic (no effect on the shipped GTAP models)
• Custom and scenario shocks with duplicated or overlapping rows were accepted and could shock elements never specified
• Redeploying within the same minute appended to the existing shock file
• A user shock file with an argument-less uniform shock shocked only the variable’s first element (solver 1.1.0)
• A uniform shock on a scalar variable declared without sets was written as Shock phi(NA)
• GTAP-RE: the PVALFWDTIME discount did not scale with time-step length

Platform

• On Linux the solver container runs as the calling user (previously failed for users other than uid 1000)
• Deploy paths containing spaces work
• A deploy directory accepts one solve at a time
• Ctrl-C stops a running solve: the solver container is removed and the run is reported as interrupted (previously the solve ran on and was reported as a failure)

teems 0.1.1

• ems_example() example typo fixed
• verbatim tests for all exported function examples added

teems 0.1.0

• write_dir removed from ems_deploy(), default write directory now tempdir() and can be overridden via tempdir arg in ems_option_set()
• Explicit path first arg for ems_example(), with no default
• ems_example() now accepts outputs from GTAP_convert()
• GTAP_convert() inputs now har-specific
• Expanded and more descriptive examples

teems 0.0.5

• Officially submitted to CRAN
